Liquid ejecting head, liquid ejecting apparatus, and piezoelectric element
A liquid ejecting head includes: pressure generation chambers which communicate with nozzle orifices; and piezoelectric elements which induce pressure change in the pressure generation chambers and each include a first electrode, a piezoelectric body layer formed on the first electrode, and a second electrode formed on the side opposite to the first electrode of the piezoelectric body layer, wherein the piezoelectric body layer includes two dielectric films having the substantially same interstitial distance and an intervening layer provided between the two dielectric films and having a different interstitial distance from that of the dielectric film.
