PURPOSE: To provide a heating device which can maintain the insulation, gives no fear of electric shock and can safely stop the power feeding function even in the final period of the service life of a heating body.
CONSTITUTION: This heating device 4 is composed of a sheath heater 1 to be a heating body to heat a liquid; a water pipe to pass the liquid; and a heat conductive metal part 3 to integrally connect the heating body 1 and the water pipe. By covering the water pipe 2 by an electric insulating member 7 and a metal pipe 8, the water pipe 2 is electrically insulated from the metal part 3, and furthermore, this heating device 4 is installed to the other structure of an apparatus by electrically insulating through an electric insulator.
