Abstract
A piezoelectric element with electrode is capable of preventing an assembling error. The piezoelectric element includes a piezoelectric body configured to deform according to polarity in response to a voltage applied thereto, electrodes formed on surfaces of the piezoelectric body, respectively, a non-electrode part formed on at least one of the surfaces of the piezoelectric body, the non-electrode part continuing to the one electrode that is on the at least one surface of the piezoelectric body, and a boundary between the non-electrode part and the one electrode. The boundary has a pattern to indicate the polarity of the piezoelectric element.
