HEATING COIL FOR INDUCTION HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a small size low cost induction heating device in which a low cost heating coil that is of a simple structure and capable of reducing a loss is realized. SOLUTION: A first electric conductor 11 made of plural element wires is wound in a spiral form and a second electric conductor which at least increases electric resistance of the electric conductor 11 is provided between the plural element wires and thereby an insulating material of high heat resistance which is required in the conventional art is made unnecessary, hence a low cost induction heating device is realized.
