Abstract

PURPOSE:To improve the strength of a frame body by performing the thermal processing while applying the compressing force prior to the fixing of an electrode to the frame body. CONSTITUTION:The compressing force is applied through the pressing onto a frame body to deform said frame body then said frame body is fitted to a pair of zigz 10 under this state and fixed. While heat-resistant insulators 11 are arranged at both ends at the inside of said zig 10. Thereafter the frame body fitted to the zig 10 is heated by a high frequency heating coil. During said heating the frame body is subjected to high compressing force from the zig 10. An electrode member 1 is fixed to such thermally processed frame body.
