Method of manufacturing joint body of conductive ceramic body and metal body
A method of manufacturing a joint body of a ceramic body and a metal body includes a step of joining them together by passing a current to an abutment surface between them. The joining step includes a step of heating up the abutment surface to a temperature T1 within a temperature range between (Tr-220)° C. and (Tr-50)° C. in a period longer than 10 seconds, Tr being a recrystallization temperature of the metal body, a step of heating the abutment surface for a period longer than 5 seconds at a temperature T2 within a temperature range between Tm×0.3° C. and Tm×0.45° C., Tm being a melting point of the metal body, and a step of heating the abutment surface for a period longer than 3 seconds at a heating temperature higher than Tm×0.48° C. and lower than Tm×0.6° C.
