PROBLEM TO BE SOLVED: To keep the degassing capacity of a mold preventing from a low melting point component from being solidified and accumulated in a degassing route to be deposited by regulating the temperature of the degassing route to the melting point of a volatile component or above. SOLUTION: In the mold equipped with the degassing passage 12 for discharging the gas, which is produced from the molten resin being the member to be molded charged in a cavity 7 at the time of molding, to the outside, a heater 31 for regulating the temperature of the degassing core 11 is provided to the degassing core 11 provided to the degassing passage 12 and a heater 31 is provided so as to regulate the temperature of the degassing core 11 to a temperature higher than the melting point of the gas or above.
