PROBLEM TO BE SOLVED: To provide a small and low-cost induction heating device by realizing a simple-structured inexpensive heating coil, without increasing the loss. SOLUTION: In the heating coil for the induction heating device, an electrical conductor 13 is wound around spirally separated by intervals, and a magnetic material 14 is inserted into approx, one turn part of the intervals, so that the magnetic materials are distributed continuously or separately, and the magnetic material is not inserted into at least one interval adjacent to the magnetic material. |
