PROBLEM TO BE SOLVED: To provide a far infrared heating device reducing the number of components since it is unnecessary to press a heating element to a far infrared radiation plate to be closely kept into contact therewith. SOLUTION: This far infrared heating device is provided with the far infrared radiation plate 51 formed into the angular cylindrical shape in a state where a face to which the heating element 52 composed of resisting paste is closely kept into contact, faces inward, and a heat shield plate 53 facing to an inner side face of the far infrared radiation plate 51 to form a ventilation passage 54.
