The injection molding method for injecting a resin into a cavity formed within a mold is provided with a heating step in which the temperature of a cavity surface forming the cavity of the mold is heated to a temperature equal to or higher than a heat distortion temperature of the resin and an injection step in which after the heating step, during a decrease in temperature of the cavity surface of the mold, the resin is injected into the cavity. |
