PROBLEM TO BE SOLVED: To prevent fluctuation of an output characteristic or a temperature characteristic caused by distortion of a diaphragm by stress when a diaphragm type pressure detector is integrated into a conduit. SOLUTION: In this mounting structure of the pressure detector, the pressure detector formed by fixing integrally a diaphragm base equipped with a diaphragm and a sensor base having a built-in sensor element operated by displacement of the diaphragm is inserted through a gasket into an insertion hole of a fixture body fixed on a pipe conduit or a mechanical device, and the pressure detector is pressed and fixed gastightly by a presser member inserted into the insertion hole from the upper side. In the structure, the presser member abuts on the body part upper face of the diaphragm base and the gasket abuts on the body part lower face thereof respectively, and a shallow groove is formed in a ring shape on the inside position of the abutting part with the presser member on the body part upper face and a shallow groove is formed in a ring shape on the inside position of the abutting part with the gasket on the body part lower face, and distortion generated by pressing by the presser member is absorbed by both shallow grooves.
