ABSTRACT:
A pressure sensor comprises a housing having a pressurized fluid inlet, and a supporting member installed in an inner space of the housing and having one end surface of the pressurized fluid inlet side, the other end surface opposite to the one end surface, and a connection port opened at the one end surface and the other end surface. A pressure sensitive element is supported on the one end surface of the supporting member in the inner space of the housing to partition the inner space of the housing into a pressure sensitive chamber communicating with the pressurized fluid inlet and a sealing chamber isolated from the pressurized fluid inlet. An electric circuit module is supported on the other end surface of the supporting member in the inner space of the housing and is electrically connected to the pressure sensitive element through the connection port of the supporting member. And, an external connection terminal is supported on the peripheral wall of the housing to protrude from the inner space of the housing to the outer space, and is electrically connected to the electric circuit module.
