A projection of burr is provided by forming an appropriate gap to set a cast-in member to a cast-in mold, completely closing the gap when the cast-in mold is clamped, and correcting cast-in positioning (axis mating) to a die-cast component by a clamping operation of the die-cast mold, regardless of a dimensional precision of the cast-in member upon a manufacture. Steel plate cast-in member, wrapped cast except for a bonding portionto a steel plate bonding memberupon molding a die-cast component, has a mold contact portionat a boundary between a cast-in portionwrapped cast with a die-cast componentand the bonding portion. When a cast-in mold A is clamped, the mold contact portionis brought into butting contact with the cast-in mold A, gap S between the cast-in memberand the cast-in mold A, cavity a, is closed.
