摘要：This invention relates to a pressure nsor having an optimum structure when fitted to a wall of a hydraulic apparatus such as an oil pressure pipe and a joint and consisting of a thin sheet-like diaphragm having a strain detection portion, and a support member for storing the diaphragm with a stepped hole structure and positioning it suitably. The invention relates also to a production method of a pressure nsor, which produces a strain detection portion which is to be formed on the surface of a diaphragm, with the diaphragm of the pressure nsor formed with a thin sheet member, by utilizing effectively a miconductor fabrication technique. The prent invention relates also to a pro
duction method of a pressure nsor which joins and integrates the diaphragm and the support member described above by diffud junction and at the same time, effects joining and crystallization of a miconductor strain gauge by the heat-treatment at the time of the diffud junction. Furthermore, the prent invention relates to a hydraulic
apparatus equipped with a pressure nsor, which has a structure wherein the pressure nsor is in advance asmbled and is optimal for the environment of u.
