Abstract
A differential pressure sensor includes: a sensor module including: a sensor case including a port through which a target fluid is to be introduced and a base attached with the port; a sensor configured to detect a physical quantity of the target fluid; a sensor substrate attached with the sensor, the sensor substrate having an outer circumferential surface facing an inner circumferential surface of the base; and a cover configured to press the sensor substrate against the base; and a case body including an electric circuit that is housed therein and electrically connectable to the sensor module, the case body having an open end to which the sensor module is externally attached, in which a sensor module clearance is defined between the outer circumferential surface of the sensor substrate and an inner circumferential surface of the sensor case.
