Abstract

A piezoelectric valve (1) includes a housing (2) provided with an inflow hole (P1) and an outflow hole (P2) for air, and a valve element (3) disposed in the housing and configured to open and close the inflow hole. The valve element is configured by a piezoelectric unit (11) including a plate-shaped piezoelectric element (12) and a diaphragm (13) on which the piezoelectric element is stacked. The inflow hole does not overlap the piezoelectric element but overlaps only the diaphragm when viewed from a stacking direction of the piezoelectric element in the piezoelectric unit.
