PURPOSE:To simplify a manufacturing process, reduce fluctuation of an inductance value, improve a manufacturing yield, and make an electromagnetic induction heating cooker thin and compact by forming a pattern of a heating coil for the electromagnetic induction hating cooker on a printed circuit board together with patterns of a high frequency inverter circuit and control circuit or shielding patterns. CONSTITUTION:A pattern 3 of a swirl type heating coil is formed on a printed circuit board. Both or either one of a pattern 5 of a high frequency inverter circuit and a pattern 6 of a control circuit is provided around the pattern 3 of the heating coil. Shielding patterns 2, 2a are disposed around the pattern 3 of the heating coil together with the patterns 5a, 5b of the high frequency inverter circuit and patterns 6a, 6b of the control circuit. |
