A capacitance-type pressure sensor unit capable of being assembled without applying a pressure at an increased level to a circuit board. A connector body (,) has a base (,) received in a peripheral wall section (,) of a receiving casing (,) constituting a main body of the casing (,) and fixed to an end (,) of the peripheral wall section (,) by caulking. A pressure sensor element (,) constituted of a first insulating substrate (,) and a second insulating substrate (,) is arranged in a bottom wall section (,) of the receiving casing (,) and a fluid chamber (,) into which pressure measured fluid is introduced is defined between a rear surface of the first insulating substrate (,) and the bottom wall section (,). A circuit board (,) received in a circuit component receiving chamber (,) defined in the base (,) of the connector body (,) is supported by connection conductors (,) for connection of a connector (,), metal terminal fitments (,) for electrically connecting output electrodes (,) of the pressure sensor element (,) to a circuit board (,) and a ground terminal fitment (,) for electrically connecting a ground electrode of the circuit board (,) to the receiving casing (,) while being suspended in the chamber (,).
