摘要：
A method of producing a laminated sheet-like material, which comprises interposing an adhesive powdery thermoplastic resin composition or an air-permeable sintered product thereof between at least two sheet-like materials to form an assembly, maintaining the assembly at reduced pressure to deaerate the adhesive layer, and heating the assembly while maintaining it at reduced pressure at least at the intial stage of heating thereby to melt the powdery thermoplastic resin composition or the sintered product and bond the sheet-like materials to provide an integral body.
