description PURPOSE:To lower voltage of a noise terminal having a controlling a circuit as a noise source by installing >=2 of GND leads connecting an inverter circuit and the controlling circuit. CONSTITUTION:Additionally to a conventional first GND lead 12 led from the periphery of an emitter of a switching device of an inverter circuit, a second GND lead 13 is led from a spot having the same voltage of the emitter of the switching device and except a part of a loop in which a high frequency current flows. The second GND lead 13 works to stabilize the voltage of a controlling circuit 11 against ground and weakens the function of the controlling circuit as a noise source. Consequently, voltage increase of a noise terminal is suppressed even when a part of a controlling circuit 11 such as a power setting and displaying unit of a built-in type induction heat cooking appliance is separated from a controlling circuit main body and connected with the main body by a long lead wire.
