<p>An induction heating cooker is provided with an induction heating coil (3), an inverter circuit (12), an infrared sensor (4) that measures the temperature at the bottom of the cooking container, and a controller (17) that controls the output power of the inverter circuit. The controller (17): uses a second threshold value, which is higher than a first threshold value, as a burning threshold value to begin burning detection when the temperature is less than the prescribed first threshold value at prescribed time points after the heating of the cooking container has started; detects burning of the contents of the cooking container when the temperature has increased to at least the burning threshold value; detects a cooking operation with respect to the contents of the cooking container when the temperature drops by at least a prescribed temperature decrease amount; and continues burning detection by using a third threshold value that is less than the second threshold value, instead of the second threshold value, as the burning threshold value when neither burning nor a cooking operation are detected within a prescribed first time period from when burning detection started.</p> |
