1. A method for manufacturing a metal-resin composite by press-molding a metal member and a resin material, the method comprising:
arranging a lower mold, the metal member, the resin material, and an upper mold in this order,
sandwiching the metal member and the resin material with the upper mold and the lower mold;
pressing the metal member against the upper mold through an elastic member attached only to a molding surface of the lower mold by the sandwiching to seal a cavity formed by the upper mold and the lower mold; and
integrating the metal member and the resin material by the press molding while sealing the resin material into the cavity.
