ABSTRACT:
The pressure sensor includes a first tubular member including at one end portion thereof a sensing section outputting an electrical signal indicative of a pressure applied thereto, and an opening section formed at the other end portion thereof, a second tubular member including an opening section formed at one end portion thereof and a diaphragm located at one end portion thereof, a housing having an opening at one end portion thereof, and a pressure transmission member operating to transmit a pressure applied thereto to the sensing section. The first and second tubular members are integrally connected to each other at their the opening sections. A fixing portion between the first and the second tubular members is located inside the housing, an outer periphery of the second tubular member is fixed to an inner periphery of the opening section of the housing.
