Abstract
Abstract A composite molded article comprising a layer 5 made of a synthetic resin on which is laminated a surface material 1 having a construction such that wood veneers 3 and 4 are laminated on the surfaces of a metal sheet 2. A method for molding a composite molded article comprises the steps of: arranging, in a metal mold 7 for molding, a surface material 1 which has a construction such that wood veneers 3 and 4 are laminated on each surface of a metal sheet 2; and molding a synthetic resin 5 on a backside of the surface material 1 to integrate the surface material 1 with the synthetic resin 5.
