Abstract
An induction heating cooking device includes a heating coil (8) that induction-heats a cooking container, an infrared sensor (10) that detects infrared radiation which is emitted from a bottom surface of the cooking container and that outputs a detection signal based on the quantity of energy of the detected infrared radiation, and a heating control section (9) that controls supply of electric power to the heating coil based on the detection signal. When the temperature of the bottom surface of the cooking container is equal to or higher than a first predetermined temperature which is higher than 230 degrees C., the infrared sensor (10) outputs the detection signal, and when the bottom-surface temperature is lower than the first predetermined temperature, the infrared sensor (10) does not output the detection signal substantially.
