PROBLEM TO BE SOLVED: To provide an induction heating device for reducing a low-frequency magnetic field included in a heating coil. SOLUTION: The induction heating device comprises a load 2; a heating coil 5 magnetically combined with the load 2; an invertor circuit 11 for supplying power to the heating coil 5 and a power supply for supplying power to the invertor circuit 11. By connecting a high-frequency transformer 12 of which the primary winding 13 is connected to the invertor circuit 11 and the secondary winding 14 is connected to the heating coil 5 to the device, a low-frequency component can be cut, and the impression of a current having a frequency component of the power supply on the heating coil 5 can be reduced.
