The pressure is applied when one electrode surface contacts the other electrode surface of the piezoelectric element 2, which is electrically connected to the external cable 7 that is inserted in an insulated state through the small-diameter shaft hole 111b extending from the stepped seat surface. The outer periphery of the diaphragm 6 joined to the transmission rod 5 is connected to the pressure-receiving end surface 11 of the metal shell 1.
a, the pressure sensitive part 61 which is joined to the pressure transmission rod 5 of the diaphragm 6 is joined to the pressure-receiving end surface 11a of the metal shell 1, and the piezoelectric element is connected to the outer peripheral part 62 which extends forward. 2. A pressure sensor characterized by being retracted in the direction 2 and having a thinner wall than the outer circumferential portion 62.
