Beschreibung
Zusammenfassung:	A glow plug with a combustion pressure sensor is improved in airtightness between the same and a combustion chamber. The glow plug 100 includes a housing having a substantially tubular metallic shell extending in an axial direction and a substantially tubular cap member which is provided at the front end of the metallic shell, which is shorter in length along the axial direction than the metallic shell, and whose diameter decreases toward the front end thereof, a heater unit, a connecting member, and a pressure sensor. The cap member is formed of a material higher in tensile strength or yield strength than a material used to form the metallic shell, and the metallic shell is formed of a material higher in thermal expansion coefficient than that used to form the cap member.
