Abstract

PURPOSE:To make lowering of strength and a heat impact property, etc., of ceramic as a base substance to be eliminated as well as dispersion of the resistance value of an exothermic coil to be reduced by forming lead parts for an electrode ejection with a conductive ceramic. CONSTITUTION:An exothermic coil 14 and lead parts 12 and 13 for an electrode ejection formed with a conductive ceramic are buriedly provided in a ceramic sintered body 15', and each end part 12-1 and 13-1 of parts 12 and 13 is nakedly exposed on the outer surface of the body 15'. The coil 14 and parts 12 and 13 are buriedly provided in a preformed groove. This allows a shape to be fixed and the dispersion of a resistance value of the coil 14 reduced. Moreover, the strength and heat impact property of ceramic is improved since lead parts 12 and 13 too are baked and integrated concurrently with ceramic 15' as a base substance and heat expansion coefficients are practically equal.
