PURPOSE: To improve convenience of use by providing a power receiving coil electromagnetically coupled to a heating coil of constituting an iduction heating cooking device and a display device for displaying condition of high frequency power induced in the power receiving coil, so that an input condition can be directly discriminated and also the device can be set to a condition of the best efficiency.

CONSTITUTION: A display device 2, which is additionally provided in an electromagnetic induction equipment in the past to display a condition of high frequency power, is provided. That is, the display device 2 is mounted partly to a side surface of the induction equipment 1, in which a power receiving coil 3 is stored in the bottom surface, and left as connected to a circuit 7 of driving this device by the high frequency power induced in the coil 3. Here, it is the same as in the past that high frequency power is generated in the receiving coil 3 by a line of magnetic force from a cooking device 11 to perform rotary cooking with the electromagnetic induction equipment 1 by this power, but here simultaneously through the circuit 7, the power generated in the coil 3 is displayed in the display device 2. By a constitution thus provided, since the device 2 is the lightest by inducing the power in the coil 3 the most efficiently when the equipment 1 is positioned in the electromagnetic center part of the cooking device 1, the device 2 is effective for also detecting a good position.
