 wherein at least one or more triaxial woven fabrics impregnated with a resin and one or more non-woven fabrics impregnated with a resin are mutually laminated in a state where the resins are not completely cured, and thereby a composite material is formed;    the composite material is laid-up in a mold; and    the resin of the laid-up composite material is cured, and thereby a molded body is formed.    
     
     
         12 . A molded body: 
 wherein at least one or more triaxial woven fabrics impregnated with a resin and one or more non-woven fabrics are laminated in a state where the resin of the triaxial woven fabric is not completely cured, and thereby a composite material is formed;    the composite material is laid-up in a mold; and    the resin of the laid-up composite material is cured, and thereby a molded body is formed.    
     
     
         13 . A molded body: 
 wherein at least one or more triaxial woven fabrics and one or more non-woven fabrics are laminated, and thereby a laminated body is formed;    the laminated body, while impregnating with a resin, is laid-up in a mold; and    the resin of the laid-up laminated body is cured, and thereby a molded body is formed.    
     
     
         14 . A molded body: 
 wherein a non-woven fabric is laminated with a triaxial woven fabric impregnated with a resin, and thereby a laminated body is formed; and    the laminated body is laid-up followed by curing the resin, and thereby a molded body is formed.    
     
     
         15 . A molded body as set forth in any one of claims  10  through  14 : 
 wherein the non-woven fabric has electrical conducting properties.  
 
     
     
         16 . A molded body as set forth in any one of claims  10  through  14 :
