Abstract

Metal plates having respective adhesive layers are put one on one with their adhesive layers inside, and pressed and punched by a metal mold assembly. After the upper plate is separated by a predetermined distance from the lower plate, molten synthetic resin is poured into a cavity between the two metal plates by injection molding, thereby forming a composite member of the metal plates and the synthetic resin. A projected portion which is connected to the synthetic resin layer can be formed through a hole made by punching work.
