Ceramic member-electric power supply connector coupling structure
 A ceramic member-electric power supply connector coupling structure includes a ceramic member with a hole and is provided with a metallic member therein so as to be partially exposed to the hole. An electric power supply connector and a tubular atmosphere-shielding member are provided in the hole. Further, a stress-mitigating, low heat expansion conductor is provided inside the atmosphere-shielding member and the power supply connector is partially positioned therein. The atmosphere-shielding member is gas-tightly joined to the power supply connector, and the expansion conductor and the tubular atmosphere-shielding member are joined to the metallic member. The coupling structure has high heat and corrosion resistance, high joining strength, and remains highly conductive even at high temperature conditions in an oxidative or corrosive environment.
