To provide a device neither requiring any electrical conductive layer nor electrical conductor.

An induction heating device in stalled within a vacuum container 6 for performing an induction heating of material 3 to be heated by energizing a coil 16 is constructed such that an outside part of an insulating covering layer 4B insulating an electrical conductor 4A of the coil 16 is covered by a resistor layer 4D, the resistor layer 4D is connected to a ground and inter- layers of the coil 16 are closely wound from each other.
