Abstract

A piezoelectric valve (1) is a piezoelectric valve driven by a DC component, and includes a plurality of piezoelectric elements (12A, 12B) electrically connected in parallel via electrodes (14) made of a metal-plated film; a conductive diaphragm (13) joined to the plurality of piezoelectric elements via the electrodes; and a resistor (22) electrically connected to the plurality of piezoelectric elements, and an electric resistance value (R1) of the resistor is less than an insulation resistance value (R2) of each of the piezoelectric elements.
