Patent ID: 7370536

Claim:
A pressure sensor device comprising: a pressure sensor cell comprising: a pressure sensor chip having a pressure receiving section for receiving pressure and means for converting strain of the pressure receiving section into an electrical signal; a base member having a first face, a second face, and a through hole extending through the first and second faces; pressure introducing means having a first face, a second face, and a through hole penetrating through the first and second faces; a resin case having a signal terminal for outputting the electrical signal from the pressure sensor chip; a joining member joining the pressure introducing means and the base member; and at least one of a protective member or a filler, wherein the pressure sensor chip is joined to the second face of the base member with the pressure receiving section facing the through hole of the base member, wherein the joining member joins the second face of the pressure introducing means to the first face of the base member with the through hole of the pressure introducing means communicating with the through hole of the base member, wherein one of the protective member or filler covers the joining member, wherein the resin case is bonded to the pressure introducing means with an adhesive, and wherein the pressure sensor chip and the signal terminal are electrically connected together by wire bonding.
