Abstract (en)
A glow plug (100) is provided having a combustion pressure sensor capable of detecting combustion pressure with high accuracy over a long period of time. A heater support member (10) for supporting a heater (20) has a movable or elastically deformable portion (12), which is located forward of a seat face (7); i.e. the movable or elastically deformable portion (12) is substantially exposed forward of a housing (1). The movable portion (12) has the function to allow axial displacement of the heater (20) through elastic deformation in response to combustion pressure applied to the pressure-receiving surface of a forward end of the heater (20).
