That is, in this method, first, thermoplastic resin films are laminated on both sides of a mat-like material mainly composed of inorganic fibers. Then, this laminate is heated and then compressed to impregnate the inside of the mat-like material with the molten thermoplastic resin. Thereafter, the thermoplastic resin is expanded in a molten state to increase the thickness of the laminated sheet, and then cooled to obtain a composite material.
