Summary:PROBLEM TO BE SOLVED: To provide an induction heating device which stably heats even when a resonance frequency is sharply changed by the movement or the like of an object to be heated. SOLUTION: On the induction heating device, a control means 40 increases the output of an inverter 31 by reducing a driving frequency, and reduces the output of the inverter 31 by increasing the driving frequency of the inverter 31 when a detected result of a short circuit mode detecting means 48 detects the short circuit mode.
