摘要： PROBLEM TO BE SOLVED: To provide a laminated molded article capable of preventing the erosion of a cushion layer caused by a molten resin for a core material by a simple means without deteriorating the moldability of a surface layer or the like. SOLUTION: The surface layer 11 and the cushion layer 12 are laminated to be set to a female mold 31 (first mold) so that the surface layer 11 faces to the molding surface 31a of the female mold. The molding surface 32a of a male mold 32 (second mold) is covered with a net 14. The female and male molds 31, 32 are allowed to approch each other to hold the net 14 between the cushion layer 12 and the male mold 32. Next, the gap between the molding surface 32a and the net 14 is filled with the molten resin 13' having to become the core material 13. The molten resin 13' presses the net 14 to the cushion layer 12 and a part 13a thereof adheres to the cushion layer 12 through the meshes 14a of the net 14.
