         4 . The plate type thin heat pipe of  claim 3 , additionally comprising a second plurality of spaced apart metal wire members placed in parallel and in substantially the same plane and placed so as to cross said plurality of first metal wire members.  
     
     
         5 . A plate type thin heat pipe, comprising: 
 a group of wire members comprising a first substantially planar array of spaced apart metal wire members, and a second substantially planar array of spaced apart metal wire members, wherein said second array is placed so as to cross said first array;    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 to receive said wire members 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, said group of wire members being received in said hollow portion and each of inner surface of said upper plate member and said lower plate member contacting at least some of said wire members; and    water as a working fluid received in said container.    
     
     
         6 . The plate type thin heat pipe of  claim 5 , wherein said upper plate member is integrally formed as a single piece member by press-working.  
     
     
         7 . The plate type thin heat pipe of  claim 5 , further comprising: 
 a plurality of protruding portions being formed on an inner surface of said upper plate member or said lower plate member;    said wick received in said container in such a manner that said wick is pressed by said plurality of protruding portions to an opposing inner surface of said container.    
     
     
         8 . The plate type thin heat pipe of  claim 5 , wherein said wick comprises a unit of punched metal plates formed by combining two punched metal plates in which at least one of said punched metal plates have a plurality of protruding portions, and said two punched metal plates are placed face to face with a distance corresponding to a height of said protruding portion and a wire member wound around said unit of punched metal plates;  
     
     
         9 . The plate type thin heat pipe of  claim 8 , wherein another wire member is further arranged in such manner that said another wire member crosses said wire member arranged on both of outer surfaces of said unit of punched metal plates of said wick.  
     
     
         10 . The plate type thin heat pipe of  claim 9 , wherein said upper plate member is integrally formed as a single piece member by press-working.  
     
     
         11 . A heat transfer apparatus comprising: 
 a first plate member;    a second plate member;    a first plurality of wire members arranged in parallel and disposed between said first plate member and said second plate member; and    a second plurality of wire members arranged perpendicular to said first plurality of wire members and disposed between said first plurality of wire members and said second plate member.    
     
     
         12 . The apparatus of  claim 11 , further comprising: 
 a third plate member disposed a predetermined distance from said second plate member;    a fourth plate member;    a third plurality of wire members arranged in parallel and disposed between said third plate member and said fourth plate member; and    a fourth plurality of wire members arranged perpendicular to said third plurality of wire members and disposed between said third plurality of wire members and said fourth plate member    
     
     
         13 . The apparatus of  claim 11 , further comprising a protruding portion disposed between said second and third plate members.  
     
     
         14 . The apparatus of  claim 11 , further comprising a fluid disposed between said second and third plate members.  
     
     
         15 . A method of manufacturing an electronic cooling device comprising:
