Abstract

PURPOSE: To cheaply obtain a central electrode without any opening between a sleeve of corrosion-resistant metal and a core of high thermal conductivity metal by loosely fitting a fitted portion of the high thermal conductivity metal in a hole of the corrosion-resistant metal and by tightly fitting the fitted portion in the hole and by extruding these fitted metals to a predetermined small diameter.
