To provide an induction heating cooker giving no inconvenience to a user when cooking is performed at a plurality of heating parts simultaneously.
An induction heating cooker comprises: an inverter circuit supplying power to a heating coil 6; an oven 5 with heating means; an on-off circuit 706 supplying power to the heating means; a voltage detector 712 detecting an AC commercial power supply voltage; and a controller 713 controlling the on-off circuit 706 on the basis of a detection result of the voltage detector 712. When a supply of power to the heating means is requested and cooking is performed, the controller 713 supplies the power to the heating means for a time period longer than a time period for cooking performed at a rated voltage in the case that a voltage detected by the voltage detector 712 is lower than the rated voltage, and supplies a power lower than the power supplied at the rated voltage to the heating means in the case that the voltage detected by the voltage detector 712 is higher than the rated voltage.
