Abstract
A piezoelectric valve is a piezoelectric valve driven by a DC component, and includes a plurality of piezoelectric elements electrically connected in parallel via electrodes made of a metal-plated film; a conductive diaphragm joined to the plurality of piezoelectric elements via the electrodes; and a resistor electrically connected to the plurality of piezoelectric elements, and an electric resistance value of the resistor is less than an insulation resistance value of each of the piezoelectric elements.

A piezoelectric valve driven by a direct-current component, the piezoelectric valve comprising:
- a plurality of piezoelectric elements electrically connected in parallel via electrodes made of a metal-plated film;
- a conductive diaphragm joined to the plurality of piezoelectric elements via the electrodes;
- and
- a resistor electrically connected to the plurality of piezoelectric elements,
- wherein an electric resistance value of the resistor is less than an insulation resistance value of each of the piezoelectric elements.
