Patent ID: 7412894

Claim:
A pressure sensor cell comprising: a pressure sensor chip having a pressure receiving section for receiving pressure and a converting unit for converting strain of the pressure receiving section to an electric signal, the strain being exerted by the pressure received by the pressure receiving section; a base member having a first face, a second face, and a through hole extending through the first face and the second face; a metallic pressure introducing unit having a first face, a second face, and a through hole extending through the first face and the second face; and a resin case having a signal terminal for outputting the electric signal from the converting unit of the pressure sensor chip, wherein the pressure receiving section faces the through hole of the base member, and the pressure sensor chip is joined to the second face of the base member, wherein the through hole of the pressure introducing unit communicates with the through hole of the base member, and the second face of the pressure introducing unit is joined to the first face of the base member, wherein the resin case is bonded to the pressure introducing unit, and wherein the pressure sensor chip and the signal terminal are electrically connected by a wiring.
