    • It is an object of the present invention to provide a highly-reliable induction heating cooker capable of considerably reducing erroneous detection of boiling over of a cooking container generated at the time of cooking. The induction heating cooker includes a boiling over detecting portion to reduce a heating output of an inverter to a predetermined value when a change amount of electrostatic capacitance detected by an electrostatic capacitance detecting portion with respect to a reference value reaches an output reducing threshold value or more, and the boiling over detecting portion stops a heating action or reduces the heating output to a third set value lower than a second set value when a change rate of the detected electrostatic capacitance reaches a predetermined change rate or more, and maintains the heating output at the second set value when the change rate of the detected electrostatic capacitance is less than the predetermined change rate, during a boiling over determining period started from the time when the change amount of the detected electrostatic capacitance with respect to the reference value reaches the output reducing threshold value or more.
