Abstract: A variable member is connected to a rod-shaped member and connected to a tube portion to ensure airtightness within a housing, and deforms when the rod-shaped member is displaced relative to the housing along an axial direction. A position of the connection between the tube portion and the variable member in the axial direction is a position shifted from a rear end of a gap toward a front side by a predetermined length or a position at the front side with respect to the position shifted by the predetermined length. The predetermined length is a length which is 50% of a length of the gap in the axial direction.

Abstract: A glow plug with a pressure sensor including a heater member (4) having a heating element (9) disposed therein and projecting from a forward end of a metallic shell (2), a center rod (3) having, at its forward end, a connection portion (3A) to which a rear end portion of the heating element (9) is connected, and an annular clearance CR formed between the metallic shell and the heater member in a region located on the forward end side of a junction portion (14A) of a deformable member (14) joined to the heater member. A portion of the heating element located on the forward end side relative to the forward end of the connection portion is at least partially located on the radially inner side of the clearance CR, and the forward end of the connection portion is located on the forward end side relative to the forward end of the junction portion.
