PROBLEM TO BE SOLVED: To provide an induction heating device which can display an effect in use capable of obtaining objective heating distribution by removing mutual interference in the case of simultaneous induction heating by a plurality of heating coils. SOLUTION: A device is provided with first/second heating coils 1, 2A, 2B directing a coil surface to a heating location respectively of a heated object 10 and first/second power sources D1, D2 outputting high frequency power of respectively different frequency. In the first heating coil 1, power is fed by the first power source D1. The second heating coils 2A, 2B, with power fed by the second power source D2, are a heating coil of the same dimension, to be positioned in a location symmetrical relating to the center of the first heating coil 1, the second heating coils are connected in series in a direction mutually canceling induction electromotive force generated between the second heating coil and the first heating coil 1. |
