Abstract (en)
To provide a ceramic heater type glow plug that can efficiently supply as little brazing material as possible to a bonded section by preventing the brazing material from entering portions other than a bonded section as much as possible when a ceramic heater and a metal outer cylinder are bonded together by brazing, and a manufacturing method thereof. A method for manufacturing a ceramic heater type glow plug including a ceramic heater and a metal outer cylinder having one end holding the ceramic heater and another end fixed by being inserted into an internal hole of a housing includes the step of forming a first metallization section so as to cover an electrode exposed on an outer peripheral portion in circumferential direction of the ceramic heater and forming a second metallization section for improving surface wettability in a position corresponding to a front end of the metal outer cylinder closer to a front end side than the first metallization section.
