       11 . The wall element of  claim 1 , characterized in that recesses ( 14 ,  24 ) are made in the base sheet ( 11 ,  21 ) for receiving elements of a supporting structure, in particular wooden posts.  
   
   
       12 . The wall element of  claim 11 , characterized in that the recesses ( 24 ) extend in depth from the surface ( 21 . 1 ) of the base sheet ( 21 ) to the insulation sheet ( 22 ).  
   
   
       13 . The wall element of  claim 1 , characterized in that the recesses ( 14 ,  24 ) are produced by milling.  
   
   
       14 . The wall element of  claim 1 , characterized in that installation ducts ( 25 ) are made in the base sheet ( 11 ,  21 ) and/or in the insulation sheet ( 12 ,  22 ).  
   
   
       15 . The wall element of  claim 1 , characterized in that a plurality of wall elements ( 10 ,  20 ) can be put together to make finished outer walls of a building.  
   
   
       16 . The wall element of  claim 15 , characterized in that the insulation sheets ( 12 ,  22 ) of the wall elements ( 10 ,  20 ) form the outsides of the outer walls and are provided with a plaster system.  
   
   
       17 . A method for manufacturing a wall element of  claim 1 , characterized in that the material of the base sheet ( 11 ,  21 ) is poured in the liquid state onto the back side ( 12 . 1 ,  22 . 1 ) of the insulation sheets ( 12 ,  22 ) and compacted.  
   
   
       18 . A method for manufacturing a wall element of  claim 1 , characterized in that the material of the base sheet ( 11 ,  21 ,  31 ) is poured into a mold and compacted, and next, the insulation sheet ( 12 ,  22 ,  32 ), moistened on the contact side with the base sheet ( 11 ,  21 ,  31 ), is placed onto the material of the base sheet ( 11 ,  21 ,  31 ).  
   
   
       19 . The method of  claim 18 , characterized in that air chambers are made in the material of the base sheet ( 11 ,  21 ,  31 ), by means of positive-displacement bodies that are located or can be located in the mold and/or by means of mixing in clumps of ice beneath thee material of the base sheet ( 11 ,  21 ,  31 ).
