Abstract
A piezo electric device having a configuration that can suppress the formation of a leakage path between electrodes that sandwich a piezoelectric layer and also reduce deterioration in the piezoelectric characteristics, is provided. The piezoelectric device has a first electrode, a piezoelectric layer, and a second electrode stacked in this order on a substrate. The first electrode and the second electrode are arranged so as not to overlap each other in the stacking direction.
