。 It consists of a heating coil connected to a DC power source, a resonant capacitor that forms a resonant circuit together with the heating coil, and a switching element for generating a resonant current in the resonant circuit, and controlling the switching element to turn on and off. In an induction heating cooker that generates a high-frequency current in the heating coil, the heating coil generates a high-frequency alternating magnetic field, and the cooking utensils placed close to the heating coil through the top plate are heated by induction. a first temperature setting means for setting a heating temperature of the cooking utensil; and a second temperature setting means for setting a predetermined temperature lower than the set temperature in the first temperature setting means. temperature setting means, this second temperature setting means, and the temperature detected by the temperature detecting means are the second temperature setting means.
When the temperature set by the first temperature setting means is reached, the switching operation of the switching element is prohibited, and the switching operation is resumed after a certain time delay, and when the detected temperature reaches the temperature set by the first temperature setting means. An induction heating cooker comprising: control means for controlling the detected temperature to be maintained at that temperature.
