Zusammenfassung:A piezoelectric actuator is formed like a rectangular flat plate, and includes a substrate layer, a lower electrode layer, a piezoelectric layer, and an upper electrode layer formed in this order from bottom to top in a thickness direction. The upper electrode layer is constituted of a plurality of electrode segments separated in a surface direction, and connection wires connecting the electrode segments which are adjoining in the surface direction.
