ABSTRACT:
A metal oxide layer is provided around a thermocouple element. The metal oxide layer is formed by preparing a sol, in which particulates of a metal oxide are dispersed, by a sol-gel method, dipping the thermocouple element in this sol, energizing the thermocouple element as a cathode for bonding the precursor particulates of the metal oxide thereto, and heat treating the same. The thermocouple according to the present invention is compact with a thin insulating layer, excellent in flexibility, and provides no gas adsorption source.
