PROBLEM TO BE SOLVED: To provide an induction heating element made of vitriform carbon and excelling in heating efficiency; and to provide a heating device. SOLUTION: In relation to an induction heating element made of vitriform carbon for carrying out induction heating by electromagnetic induction, this induction heating element made of vitriform carbon is characterized by having an infrared emission characteristic where a ratio E1/E2 of infrared emission intensity E1 of a facing surface to a heating object to infrared emission intensity E2 of a non-facing surface to the heating object exceeds 1.2. This heating device is provided with the induction heating element made of vitriform carbon and a high-frequency induction coil arrange outside the induction heating element made of vitriform carbon for making the induction heating element made of vitriform carbon execute induction heating and is characterized by heating a heating object by an infrared ray emitted from the induction heating element made of vitriform carbon by carrying a current to the high-frequency induction coil.
