Abstract

See full text

A piezoelectric actuator includes an electrode layer including a trunk portion and a plurality of branch portions branched from the trunk portion. The trunk portion includes a plurality of junction points from each of which a corresponding branch portion of the plurality of branch portions are branched, an end spaced from the plurality of junction points, and a second through hole positioned between the plurality of junction points and the end of the trunk portion. A plurality of first through holes are grouped into a first group and a second group. The first group overlaps, in a first direction, a particular area defined between the end of the trunk portion and the second through hole and the second group overlaps, in the first direction, another particular area defined between the second through hole and the plurality of junction points.
