摘要

A piezoelectric actuator includes: a piezoelectric layer formed by a film formation method so as to have orientation in a prescribed orientation direction; and a pair of electrodes, disposed on a same surface which is substantially perpendicular to the orientation direction of the piezoelectric layer, for applying to the piezoelectric layer an electric field in a direction substantially perpendicular to the orientation direction.
