A piezoelectric actuator includes a vibration plate 30 covering pressure
chambers 14 and serving also as a common electrode, a piezoelectric layer
31 arranged on the vibration plate 30 on a side opposite to the pressure
chambers 14, and individual electrodes 32. The individual electrodes are
each arranged on a surface of the piezoelectric layer 31 opposite to the
vibration plate 30, 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.
