摘要： A strain sensor is provided which includes a strain sensor, a first housing, a second housing joined to the first housing, and a pressure measuring mechanism firmly retained between the first housing and the second housing. The pressure measuring mechanism is gripped between a first face of the first housing and a second face of the second housing to measure compressive stress exerted by a cylinder head of an internal combustion engine on the first housing and the second housing. This structure improves the reliability of mechanical strength of the housings and the pressure measuring mechanism and provides flexibility in selecting the type of the pressure measuring mechanism.
