的とする。In the conventional induction heating cooker shown in FIG. 3, infrared rays radiated from the pot 12 are detected by passing through the top plate 15. In general, there is Stefan-Boltzmann's law that the infrared energy emitted from an object is proportional to the fourth power of the absolute temperature of the object, and the higher the temperature, the greater the energy emitted as infrared rays. The radiant intensity of infrared rays also depends on the emissivity of the surface of the object. The emissivity of a black body is 1, but the closer it is to the mirror surface, the lower the emissivity, and the smaller the energy of infrared rays emitted even at high temperatures. Therefore, even if the infrared sensor measures the intensity of infrared rays radiated from the pot bottom, an accurate temperature cannot be calculated unless the emissivity of the pot bottom is known. The present invention aims to solve such conventional problems.
