PROBLEM TO BE SOLVED: To provide an infrared temperature sensor used, for example, in an electromagnetic range or the like, and capable of measuring a temperature accurately at high precision without being affected by a difference in emissivity of a heated object. SOLUTION: A substance (black body material) of high absoptivity and emissivity in an infrared wavelength is applied or contained in a translucent heat-resistant member 2 as a table to form a black body material layer 5, heat from the heated object 1 heated by an induced current in a magnetic field of an induced heating source 4 is transmitted to the black body material layer 5 at first, and an infrared ray radiated from the black body material layer 5 is detected by an infrared detector 3 to measure a temperature of the heated object 1. |
