To provide an induction heating device to realize security and high-reliability in an equipment having a switching means to switch a resonance capacitor.
This is equipped with a plurality of capacitors constituted in series and parallel connection with a first resonance capacitor 12, the switching means 13 which is connected in parallel with the plurality of capacitors and switches short-circuit/opening, a serial capacitor body of a second resonance capacitor 14 connected in series, and a resonance voltage detecting means to detect the resonance voltage value. In an opening state of the switching means 13 and in the case an output value of the resonance voltage detecting means exceeds a prescribed value, stopping of the inverter is carried out. By this, the induction heating device to realize the security and the high-reliability can be realized.
