Summary:PROBLEM TO BE SOLVED: To increase the selectivity of an adhesive while suppressing the reduction in detection accuracy.SOLUTION: In the pressure sensor, a joint member 50 formed by mixing a plurality of spherical beads 52 into an adhesive 51 is disposed between a sensor unit 10 and a member 40 to be mounted. The thickness of the adhesive 51 is made thicker than the Young's modulus [MPa] of a 20.7 [μm/MPa] × adhesive. 【課題】検出精度の低下を抑制しつつ、接着剤の選択性を高くする。【解決手段】センサ部１０と被搭載部材４０との間に接着剤５１に球状の複数のビーズ５２が混入されてなる接合部材５０が配置された圧力センサにおいて、接着剤５１の厚さを２０．７［μｍ／ＭＰａ］?接着剤のヤング率［ＭＰａ］より厚くする。【選択図】図３
