| description | [Objective] To provide a combustion pressure sensor in which a connection member and a housing are firmly welded and to provide a glow plug-cum-combustion pressure sensor, a method of manufacturing the combustion pressure sensor, and a method of manufacturing the glow plug-cum-combustion pressure sensor. [Means for Solution] A combustion pressure sensor 1 includes a tubular housing 100 extending in an axial direction DX, a displacement member 130 disposed within the housing, and a tubular connection member 160 which elastically connects the displacement member to the housing. The combustion pressure sensor has a housing weld W1 which is formed by energy-beam-welding the housing and the connection member annularly in a circumferential direction while the housing and the connection member are separated from each other at least partially in the circumferential direction and which includes, in a longitudinal section of the combustion pressure sensor, a wedged weld resulting from wedgewise melting of a portion of the housing. At least a circumferential portion of the housing weld is a bulge housing weld RW1 which bulges, with respect to a first adjacent portion 176, in a direction directed from a second adjacent portion 196 toward the first adjacent portion along a radial direction DR. |
