         2 . A plate type thin heat pipe comprising: 
 a container having a hollow portion which is reduced in inner pressure and hermetically sealed, formed by an upper plate member comprising a thin copper plate and a lower plate member comprising a thin copper plate;    a wick comprising a substantially planar array of wires received in said container; and    a working fluid received in said container.    
     
     
         3 . The plate type thin heat pipe of  claim 2  wherein said wick comprises a flat plate member and a wire member wound around said flat plate member.  
     
     
         4 . The plate type thin heat pipe of  claim 2  wherein said wick is formed by being arranged on an inner surface of one of said upper plate member and said lower plate member.  
     
     
         5 . The plate type thin heat pipe of  claim 4  wherein said wick is received in said container in such a manner that said wick is pressed by a plurality of protruding portions formed in one inner surface of said container to an opposing inner surface of said container.  
     
     
         6 . A plate type thin heat pipe comprising: 
 a container having a hollow portion formed by an upper plate member made of thin copper plate, in a central portion of which a recessed portion is formed and in a corner portion of which a passage connecting said recessed portion to outside is formed, and a flat lower pate member made of thin copper plate, outer peripheral portion of which are joined and said passage is caulked so as to be hermetically sealed and inner pressure thereof is reduced;    a wick received in said container;    a working fluid received in said container.    
     
     
         7 . The plate type thin heat pipe of  claim 6  wherein the wick comprises a flat plate member and a wire member wound around said flat plate member.  
     
     
         8 . A method of making a heat pipe comprising: 
 forming first and second metal plates, said first plate being formed with a recessed portion in a central portion thereof and a passage formed in a corner portion of an outer peripheral portion thereof,    brazing said outer peripheral portion of said first flat plate to said second flat plate; and    caulking said passage to form a hermetically sealed hollow portion.    
     
     
         9 . The method as claimed in  claim 8 , wherein said second plate is formed with a recessed portion in a central portion thereof and a passage formed in a corner portion of an outer peripheral portion thereof.  
     
     
         10 . A heat transfer apparatus comprising: 
 a first plate member comprising a recessed portion and a plurality of protruding portions extending from said recessed portion;    a second plate member; and    a flat mesh member disposed on said second plate member, wherein said first and second plate members are connected so that said recessed portion forms a cavity and said protruding portions abut said flat mesh material.    
     
     
         11 . The apparatus of  claim 10 , wherein said flat mesh material comprises a plurality of metal wires configured in a grid pattern.  
     
     
         12 . The apparatus of  claim 10 , further comprising a plurality of flat mesh members stacked on said second plate member.  
     
     
         13 . The apparatus of  claim 10 , wherein said protruding portions are integrally formed on said first plate member.  
     
     
         14 . A heat transfer apparatus comprising: 
 a first plate member comprising a recessed portion and a plurality of protruding portions extending from said recessed portion;    a second plate member;    a plurality of wire members disposed on said second plate member; and    a flat mesh member disposed on said plurality of wire members, wherein said first and second plate members are connected so that said recessed portion forms a cavity and said protruding portions abut said flat mesh material.    
     
     
         15 . The apparatus of  claim 14 , wherein said plurality of wire members are aligned in parallel.  
     
     
         16 . The apparatus of  claim 14 , wherein said plurality of wire members comprises a first plurality of wire members that are aligned in parallel and a second plurality of wire members that are aligned in parallel, wherein said first plurality of wire members is disposed next to said second plurality of wire members so that each of said first plurality of wire members are perpendicular to each of said second plurality of wire members.  
     
     
         17 . A heat transfer apparatus comprising: 
 a first plate member comprising a recessed portion and a plurality of protruding portions extending from said recessed portion;    a second plate member; and    a wick comprising a flat plate member and a wire member wound around said flat plate member, said wick being disposed on said second plate member, wherein said first and second plate members are connected so that said recessed portion forms a cavity and said protruding portions abut said flat mesh material.    
     
     
         18 . A method of manufacturing a heat transfer apparatus comprising: 
 providing a first plate member comprising a recessed portion and a plurality of protruding portions extending from said recessed portion;    providing a second plate member;    placing a plurality of wire members on said second plate member;    placing a flat mesh member on said plurality of wire members; and    connecting said first and second plate members so that said recessed portion forms a cavity and said protruding portions abut said flat mesh material.    
     
     
         19 . The method of  claim 18 , further comprising providing a fluid between said first and second plate members.
