Claim:
1. A piezoelectric element comprising: an electrode layer including positive electrode layers and negative electrode layers, which are repeatedly stacked to alternate with each other; one or more element layers arranged between each of the positive electrode layers and each of the negative electrode layers; 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 connecting the positive electrode layers and formed to be spaced apart from the primary positive electrode connection member; at least one secondary negative electrode connection member connecting the negative electrode layers and formed to be spaced apart from the primary negative electrode connection member; a primary electrode connected to the primary positive electrode connection member and the primary negative electrode connection member and configured of a plurality of electrodes; and at least one secondary electrode spaced apart from the primary electrode and configured of a plurality of electrodes connected to the secondary positive electrode connection member and the secondary negative electrode connection member.
