Provided is a die for resin molding, wherein a cavity surface can be quickly heated without forming a temperature distribution and an arbitrary region on the cavity surface can be controlled at a predetermined temperature. A die for resin molding (1) employing an electromagnetic induction heating system, which is provided with: a high hardness metal layer (2), the upper surface of which forms a cavity surface (10); a highly heat conductive metal layer (3) that is metallurgically bonded to the lower surface of the high hardness metal layer (2), said lower surface being on the reverse side of the cavity surface (10); a magnetic metal layer (4) that is metallurgically bonded to the lower surface of the highly heat conductive metal layer (3); and an inductor (6) that is arranged on the lower surface of the magnetic metal layer (4), said lower surface being on the reverse side of the highly heat conductive metal layer (3)-side surface. The thickness of the high hardness metal layer (2) and the thickness of the highly heat conductive metal layer (3) are changed within the die so as to suppress temperature unevenness in the cavity surface (10) during the heating of the die. |
