PROBLEM TO BE SOLVED: To provide an infrared sensor which can be robust to variation in an ambient temperature to detect a temperature with high accuracy.SOLUTION: An infrared sensor 4 arranged below a heating coil 3 for detecting infrared rays irradiated from a cooking container 1 placed on a top plate 2 and transmitted through the top plate 2, comprises a light-receiving element 4a converting the received infrared rays to a current and molded with a resin 4c that cuts a wavelength of not less than a first predetermined value, and an IV conversion circuit converting a current output from the light-receiving element 4a to a voltage. |
