Abstract
PURPOSE: To prevent insulation deterioration, by using a material consisting of one or two kinds of nickel, molybdenum and tungsten and thereby reducing the amount of evaporation at high temperature.
CONSTITUTION: When one or two kinds of nickel, molybdenum, and tungsten are used as heat-generating wire of a sheath heater, a heat-generating body in which the amount of evaporation at high temperature is small and insulation deterioration is reduced, can be obtained.
