PIEZOELECTRIC ACTUATOR, LIQUID DISCHARGING APPARATUS AND METHOD FOR PRODUCING PIEZOELECTRIC ACTUATOR

摘要

There is provided a piezoelectric actuator including: a plurality of piezoelectric elements forming first and second piezoelectric element rows, and including first, second electrodes and piezoelectric portion; an electrode conductive portion; a contact section; a plurality of drive wires; and conductive wires. A part of the drive wires corresponding to the piezoelectric elements of the second piezoelectric element row are extended toward the contact section while passing between two adjacent piezoelectric elements of the first piezoelectric element row which are adjacent in the first direction. The conductive wires are arranged between two adjacent piezoelectric elements of the second piezoelectric element row, each of the conductive wires is conducted, at two locations thereof apart in the second direction, with the electrode conductive portion.
