Abstract: A multilayer piezoelectric element includes a plurality of piezoelectric layers and a plurality of metal layers stacked alternately. The plurality of metal layers include a plurality of low-filled metal layers having a lower filling rate of metal composing the metal layers than oppositely disposed metal layers adjacent to each other in a stacking direction. The plurality of metal layers may include a plurality of thin metal layers having a smaller thickness than oppositely disposed metal layers adjacent to each other in a stacking direction. Where the plurality of metal layers are composed mainly of an alloy, the plurality of metal layers may include a plurality of high-ratio metal layers having a higher ratio of a component constituting the alloy than oppositely disposed metal layers adjacent to each other in a stacking direction.
