| titleOfInvention | Piezoelectric sensor and sensing device |
| abstract | Disclosed is a technique capable of suppressing the variation of the oscillation frequency of a piezoelectric vibrator caused by adsorption of a measurement object between piezoelectric sensors and detecting the amount of the measurement object with high accuracy. A piezoelectric sensor according to the present invention includes a recess for accommodating a conductive adhesive at a portion of a wiring board where an extraction electrode on the back side of a piezoelectric vibrator and an electrode on the wiring board face each other. The conductive adhesive in the recess and the extraction electrode are bonded in a state where the peripheral portion of the piezoelectric piece is in close contact with the wiring board, and the extraction electrode and the electrode are electrically connected. Yes. In this way, the stress applied to the piezoelectric piece by the crystal pressing member is uniformly applied within the surface of the piezoelectric piece, and there is no possibility that the stress applied to the piezoelectric piece by the crystal pressing member varies between the piezoelectric sensors. .
