PROBLEM TO BE SOLVED: To provide a molding die that can prevent resin leakage from an air vent part and ensure sufficient curing time of a resin charged into a cavity by disposing a metal film layer having a thermal conductivity higher than that of a die base material or a different member having a thermal conductivity on an outer periphery of a resin seal part. ! SOLUTION: A movable air vent piece 16 that can open and close an air passage is installed so as to face an air vent groove 2f for releasing air from a cavity recess 2a. The movable air vent piece 16 is formed with a metal film layer 17 having a thermal conductivity higher than that of a die base material or a different member having a thermal conductivity, on its end surface facing the air vent groove 2f. !
