Pressure sensor

Abstract

Provided is a pressure sensor capable of curbing the influence of heat and securing prescribed sensor precision. The pressure sensor includes: a tubular housing (10, 20); a pressure measurement member (80) accommodated in the housing and including a piezoelectric element; a diaphragm (30) including a flexible plate-shaped portion (31) secured to a distal end of the housing and a projecting portion (32) adapted to transmit a load to the pressure measurement member; and a shielding plate (40) disposed adjacent to the flexible plate-shaped portion to shield the diaphragm from a pressure medium, and the shielding plate (40) is secured to the flexible plate-shaped portion (31) by a bonding region (A) in a linear shape.
