PROBLEM TO BE SOLVED: To provide a heating device capable of prolonging its lifetime. SOLUTION: A high-temperature air spouting device 1 is composed of a body 12 of heating part accommodated in a casing 11 and an air lead-in part 13, wherein the body 12 is formed from a coil 21 to generate a magnetic field with current feed and a heating body 22 to be induction-heated by the magnetic field generated by the coil 21. The heating body 22 is configured with a major diametric pipe 23 and a number of minor diametric pipes 24 accommodated in the major pipe 23, and the major pipe 23 constitutes a passage 26 whereto the air is fed from the air lead-in part 13. A tapered portion 27 thinning toward the forefront is formed at the tip of the major pipe 23, and a jetting part 29 having a jet hole 28 is formed at the forefront of the tapered portion 27.
