ABSTRACT:
A method of manufacturing an electrical-resistance heating element includes forming sintered ceramics or calcined ceramics, forming an electrode on the sintered ceramics or the calcined ceramics, and forming a ceramic base material having mainly a high melting point metal on the electrode embedded therein, thereby forming a heating element with built-in electrode.
