摘要： To provide a piezoelectric sensor in which a first electrode for measurement and a second electrode for reference are provided apart from each other on one surface side of a piezoelectric piece and a common electrode is provided on the other surface side so as to face the first and second electrodes, and which achieves highly reliable oscillation by reducing the influence of electrical coupling between the first electrode and the second electrode. A piezoelectric sensor includes: a first electrode for measurement and a second electrode for reference provided apart from each other on one surface side of a piezoelectric piece; a common electrode provided on the other surface side of the piezoelectric piece commonly for the first electrode and the second electrode to face the first electrode and the second electrode; and an adsorption layer formed on an area, of the common electrode, to which the first electrode is projected, to adsorb a substance to be sensed. This structure prevents the first electrode and the second electrode from being electrically coupled due to the impedance of the sample fluid.
