Patent ID: 7690262

Claim:
A pressure sensor device comprising: a housing composed of a resin head and a resin pipe, one end of the resin pipe being connected to the resin head and the other end of the resin pipe being open to outside; terminals, having a first terminal and a second terminal, to be electrically connected to an outside circuit, the terminals being insert-molded in the resin head; a pressure sensor element for detecting pressure of fluid introduced into the housing through the resin pipe, the pressure sensor element being electrically connected to the first terminal and mounted on the resin head; a conductor bar embedded in the resin pipe with its first end and a second end exposed outside; and a temperature sensor element for detecting temperature of the fluid, the temperature sensor element being positioned close to the open end of the resin pipe, wherein: the first end of the conductor bar is electrically connected to the second terminal; and the second end of the conductor bar is positioned close to the open end of the resin pipe and electrically connected to the temperature sensor element through a lead wire having a diameter smaller than a predetermined diameter; a length of the lead wire is set in a predetermined range by providing the conductor bar electrically connecting the lead wire and the second terminal in the resin head; and a portion connecting the second end of the conductor bar to the lead wire is covered with protective resin potting.
