Pressure Sensor

Abstract

A purpose of the present invention is to provide a pressure sensor that uses a pressure detection element, the pressure detection element using the piezoresistive effect or similar, wherein the pressure sensor reduces distortion of the pressure detection element due to temperature changes, and allows accuracy to be increased and temperature responsiveness to be improved. A pressure sensor (100) according to the present invention includes: a pressure detection element (126) that detects the pressure of a fluid; a support member (125) that supports the pressure detection element (126); and an adhesive layer (125A) that is formed by coating an adhesive agent, and adheres and fixes the pressure detection element (126) and the support member (125), the pressure sensor being characterized in that the adhesive layer (125A) is configured from two layers, an initial curing layer (125A1) and a chip mount curing layer (125A2).
