Claim:
A resin injection mold for molding a resin, comprising: a shaped part produced by metal stereolithography in which a light beam irradiates metal powder to sinter, or to melt and solidify the metal powder, wherein the shaped part includes a plurality of low-density shaping parts having a small sintered density to allow gas to pass through the low-density shaping parts, and a vent through which the gas, comprising a heated or a cooled gas, is sent to the low-density shaping parts, or through which the gas is sucked from the low-density shaping parts, wherein the low-density shaping parts are each in contact with a resin molding part which molds a resin, and are connected to the vent, and the gas is sent from the vent through the low-density shaping parts to the resin molding part, or the gas in the resin molding part is sucked through the low-density shaping parts into the vent.
