Abstract: An induction cooking device being capable of heating one target heating object by two or more heating coils and also being capable of displaying the positions of the heating units clearly. The induction cooking device includes a control unit (11) and a plurality of light-emitting parts (21 to 24, etc.). The control unit includes a heating control unit (11a) that controls the output of an inverter circuit and a light-emission control unit (11b) that controls the light emission. When receiving a command for starting heating of one target heating object by one heating coil from an operation unit (7), the control unit turns on only the light-emitting parts provided near the outer circumference of the heating coil for starting heating, and when receiving a command for starting heating of one target heating object by two or more adjacent heating coils having centers at different positions from the operation unit (7), the control unit turns off the light-emitting parts disposed between the heating coils for starting heating out of the light-emitting parts provided near the outer circumference of each one of the heating coils for starting heating, and turns on the light-emitting parts other than the turned off light-emitting parts.
