摘要： Molding accuracy of a metal member is improved in an apparatus, a mold set, and a method for producing a metal-resin composite with a set of molds. An apparatus for manufacturing a metal-resin composite by press molding a metal member and a resin material, the apparatus including a mold including an upper mold and a lower mold sandwiching the metal member and the resin material, a molding auxiliary component detachably fixed to the upper mold so as to fill at least a part of a cavity C for arranging the resin material formed by the upper mold and the lower mold, and a drive unit that moves at least one of the upper mold and the lower mold in a vertical direction. The molding auxiliary component has a first press surface for molding the metal member. The upper mold has a second press surface for integrally molding the metal member and the resin material. A distance between the first press surface and the lower mold in a state where the molding auxiliary component is attached is shorter than a distance between the second press surface and the lower mold in a state where the molding auxiliary component is removed.
