摘要： An infrared sensor 26 is provided on a lower side of a top plate 2 to detect an amount of infrared light radiated from a heated object 20. The infrared sensor 26 outputs an detection signal having a substantially constant magnitude with respect to the temperature of the heated object 20 when the temperature of the heated object 20 is lower than a detection lower limit temperature, and outputs a detection signal having magnitude and rate of increase which become larger as the temperature of the heated object 20 becomes higher when the temperature of the heated object 20 is not lower than the detection lower limit temperature. The control unit 29 includes a storage unit 29a operable to store the output value of the infrared sensor 26 immediately after start of heating as an initial detection value, and reduces the output of the induction heating coils or stops the heating when an increased amount with respect to the initial detection value becomes greater than or equal to a predetermined value.
