A piezoelectric actuator that includes a fixed electrode in a base substrate, a dielectric layer on the surface of the base substrate, a lower electrode that is at least partially separated from the base substrate, a piezoelectric layer on the surface of the lower electrode, and an upper electrode on the side of the surface of the piezoelectric layer. At least a portion of the upper electrode or the lower electrode serves as a movable electrode, which can be moved by distortion of the piezoelectric layer caused by application of a piezoelectric drive voltage.
