PURPOSE:To increase the durable number of spots by joining a heat resistant and wear resistant composite semiconductor formed by compounding and composing metal and an oxide to the tip of an electrode tip. CONSTITUTION:A machining part 2 is machined and formed into a recessed shape on the tip of a bar-shaped electrode tip main body 1. The tip 3 of the electrode tip of the electrically conductive heat resistant and wear resistant composite semiconductor (Mo, Ni, C, CuOx, etc.), is embedded therein. The composite semiconductor of the metal and oxide is thermally sprayed on the machining part 2 to form the tip 3 or the tip 3 of the tip formed by a sintering press, etc., in advance can be fitted and joined into the machining part 2 to form the tip 3 as the forming method of the tip 3 of the tip. Consequently, the durable number of spots can be increased. |
