PURPOSE: To provide the composite molding method for a metal and synthetic resin which does not expose the end of a film-like molding to the end of the composite molding and the composite molding.
CONSTITUTION: This composite molding method for the metal and the synthetic resin consists in producing the composite molding 29 of the metal 27 and the film-like molding 9 by integrally molding a foamed molding 11 around the film-like molding 9 consisting of a synthetic resin material to form an expandable pattern 13 and pouring the molten metal therein. The end of the film-like molding 9 is formed shorter than the end of the composite molding and a supporting member 23 is inserted and inscribed into the hollow part of the film-like molding 9 to support the hollow part so that only the expandable beads are packed into the end of the composite molding 29 at the time of disposing the film-like molding 9 into a mold, packing the expandable beads between the mold and the film-like molding and expanding the beads by heating. The film-like molding 9 is formed shorter than the end of the composite molding 29 in this end and is formed of only the metal.
