圧力センサ。[Claims for Utility Model Registration] A composite body having a T-shaped cross section and a through hole formed in the axial direction, and a diaphragm attached to one support part via a disk and disposed within the through hole of the body. A pressure sensor comprising a tuning fork vibrator and a cap attached to the body, having a pressure introduction hole for guiding pressure to the diaphragm, the diaphragm being screwed into the pressure introduction hole of the cap to prevent the diaphragm from responding to low input pressure. A pressure sensor characterized by being provided with a stopper that stops the displacement of the pressure sensor.
