ABSTRACT:
A detecting element having desired values for electrical resistance and resistance temperature coefficient can be obtained in a simple manner by a method wherein an electrically conductive member is arranged on a substrate, a metal lead is fixed to the substrate in order to connect the electrically conductive member to an external circuit through the metal lead, and the electrically conductive member is subjected to a heat treatment. Specifically, an electrical current is passed through the electrically conductive member to heat the detecting element before completion to a predetermined temperature and to form a glass protecting film by the heat generation of the member itself.
