A pressure sensor comprises a housing having a pressure introduction hole, a pressure detecting element formed of a semiconductor device having the piezoelectric resistance effect, a holder for fixing the pressure detecting element, and a connector case. The pressure detecting element and the holder are airtightly joined to form a pressure sensor body in which an interior space is defined. A circuit board having an electrode pad is provided on the holder of the pressure sensor body, and a connector in the connector case and the electrode pad are connected by means of an electrically conductive spring body having elasticity. The holder is supported in the housing by means of a guide frame and an O-ring. |
