Piezoelectric element and electronic component including the same

摘要

A piezoelectric element includes an element layer, an electrode layer including one or more positive electrode layers and one or more negative electrode layers repeatedly stacked to alternate with each other on the element layers in a vertical direction, a primary positive electrode connection member connecting the positive electrode layers, a primary negative electrode connection member connecting the negative electrode layers, at least one secondary positive electrode connection member, at least one secondary negative electrode connection member, and a primary electrode connected to the primary positive electrode connection member and the primary negative electrode connection member and configured of a pair of electrodes, and at least one secondary electrode spaced apart from the primary electrode and configured of a pair of electrodes.

1. An electronic component comprising:
a vibration transferring member transferring vibrations; an elastic member coupled to the vibration transferring member; and a piezoelectric element mounted on the elastic member and being deformed in response to power applied thereto, wherein the piezoelectric element comprises: a primary electrode configured of a plurality of electrodes; one or more secondary electrodes configured of a plurality of electrodes and spaced apart from the primary electrode; an electrode layer including one or more positive electrode layers and one or more negative electrode layers repeatedly stacked so as to alternate with each other; one or more element layers arranged between the positive electrode layer and the negative electrode layer; a primary positive electrode connection member connecting the positive electrode layers to each other; a primary negative electrode connection member connecting the negative electrode layers to each other; one or more secondary positive electrode connection members connecting the positive electrode layers to each other and formed to be spaced apart from the primary positive electrode connection member; and one or more secondary negative electrode connection members connecting the negative electrode layers to each other and formed to be spaced apart from the primary negative electrode connection member.
