PROBLEM TO BE SOLVED: To provide a small and low-cost induction heating device by realizing a simple-structured, inexpensive heating coil capable of reducing the loss, especially in the high-frequency range. SOLUTION: An electrical conductor 11 is wound around in spiral form, and by using the stray capacitance, generated between the lines as a resonant capacitor, a resonant capacitor, which is originally a separate part, is dispensed with; and moreover, by reducing the increase of the resistance in the high-frequency range, the inexpensive and loss-reducing induction heating device can be realized. |
