PROBLEM TO BE SOLVED: To enhance the heat efficiency of a heating device for heating a mold. SOLUTION: A heater unit 33 has the reflecting plate 35, which has the reflecting surface 37 on the side of a fixed mold 5 opposed to the molding surface 5a of the fixed mold 5 and the reflecting surface 39 on the side of a movable mold 7 opposed to the molding surface 7a of the movable mold 7, and the halogen heaters 41 respectively arranged in the vicinity of both reflecting surfaces 37 and 39. A heater case 13 has the heater unit 33 built therein, and the irradiation port 17 on the side of the fixed mold 5, which is formed on the side of the reflecting surface 37 on the side of the fixed mold 5 so as to correspond to the molding surface 5a on the fixed mold 5, and the irradiation port 19 on the side of the movable mold 7 formed on the side of the reflecting surface 39 on the side of the movable mold 7 so as to correspond to the molding surface 7a on the side of the movable mold 7, are opened to the heater case 13. The molding surface 5a on the side of the fixed mold 5 and the molding surface 7a on the side of the movable mold 7 are respectively irradiated and heated using the heater unit 33 through the irradiation port 17 on the side of the fixed mold 5 and the irradiation port 19 on the side of the movable mold 7.
