Abstract
A pressure sensor includes: a pressure sensor element; a metal adapter integrally attached to the pressure sensor element and defining therein a hole through which a pressure of a fluid to be measured is introduced to the pressure sensor element; a metal fitting member provided with a housing recess receiving the adapter and connectable to a connected member; and an operation member pressing a valve provided to the connected member and defining a communicating path through which a flow path, in which the pressure of the fluid to be measured is introduced, is in communication with the hole of the adapter. The adapter and the fitting member are connected to each other by plastic deformation. The operation member is a synthetic resin member including: a contact portion brought into contact with the adapter; and a pressing portion provided on a side opposite to the contact portion to press the valve.
