PURPOSE: To provide an electromagnetic cooker constituted in such a manner that the heating pattern is improved to a large pan and a reduction in heating power or leak magnetic field is caused to a small pan. CONSTITUTION: One flat spiral coil is electrically divided by terminals S1, S2, S1A, S2A to form an inside coil 11 and an outside coil 12, and a high frequency power is independently outputted from high frequency power generating circuits 2A, 2B to each coil 11, 12. The output timings of the high frequency power generating circuits 2A, 2B are controlled by use of a control circuit 3, and the high frequency power to each coil 11, 12 is alternately switched so that duty ratio, output time interval, or combination thereof can be optionally regulated. |
