ABSTRACT:
A piezoelectric actuator includes a vibration plate30covering pressure chambers14and serving also as a common electrode, a piezoelectric layer31arranged on the vibration plate30on a side opposite to the pressure chambers14, and individual electrodes32. The individual electrodes are each arranged on a surface of the piezoelectric layer31opposite to the vibration plate30, in an area overlapping with an edge portion of the pressure chamber as viewed from a direction orthogonal to a plane in which the pressure chambers are arranged, the edge portion being an area other than the central portion of the pressure chamber. The individual electrodes are extended up to an area outside of the pressure chambers, as viewed from the direction orthogonal to the plane. A liquid transporting apparatus including the piezoelectric actuator has an excellent durability and improved drive efficiency.
