In order to provide an induction heating cooker capable of preventing a phenomenon that a drive circuit is stopped or a high-frequency current is reduced because boiling over is erroneously determined due to a fluctuation in electrostatic capacitance during cooking, the induction heating cooker includes an inverter (2) for supplying a current to a heating coil (8), a control portion (4) for driving the inverter (2), an electrostatic capacitance detecting portion (13) for measuring electrostatic capacitance of a plurality of electrodes (7), and a boiling over detecting portion (15). The boiling over detecting portion (15) reduces an output of the inverter (2) from a first set value to a second set value after a sensed value of the electrostatic capacitance has reached a range of a first variation (”V1) or more, and returns the output of the inverter (2) to the first set value when a sensed value during a boiling over establishing period (T2) performed after the sensed value has reached the first variation or more falls within a range of a second variation (”V2). |
