Abstract

A glow plug which includes an intermediate shaft (3) inserted into a shaft hole (43) of a metal shell (4) and having a connecting end part (36) of a rear end part (32) protruding from a rear end surface (48). An insulating member (6) is arranged between the intermediate shaft (3) and the shaft hole (43) of the metal shell (4). The insulting member (6) has a tapered part (63) which abuts a tapered part (47) provided in the metal shell (4). The insulating member (6) is pressed into position by a connecting terminal (5) fixed to the connecting end part (36) to assuredly hold the intermediate shaft (3) in a rear end part (45) of the metal shell (4) and to thereby prevent a deflection or bend of the intermediate shaft (3). Also disclosed is a method for manufacturing the glow plug.
