Abstract

PURPOSE: To prepare efficiently and with a low cost a resin molding with an electrically conductive layer by a method wherein when a molten resin is filled in a cavity, an electrically conductive film is broken by means of a pin provided in a recessed part for forming a projection or at a position facing the recessed part for forming a projection and a resin pressure to form a projection.
CONSTITUTION: While molds 11a and 11b are opened, an aluminum foil 17 with a thickness of 200μm is set on the inner face 13a of a cavity of one of the molds so as to cover a recessed part for forming a projection. Then, the molds 11a and 11b are closed and injection molding is performed by feeding a molten ABS resin in a cavity from a resin feeding hole 19. The aluminum foil 17 at the entrance of the recessed part 15 for forming a projection is broken by the pressure of ABS resin and an apex of a round pin 25 and as the ABS resin flows into the recessed part for forming a projection through the broken part, a projection 21 can be formed integrally with a resin molding 20. The broken piece 17a of the aluminum foil 17 becomes to be buried in the projection 21. In addition, the aluminum foil 17 becomes in a body with the resin molding 20 to obtain a resin molding 23 with an electrically conductive layer.
