A liquid-ejecting head includes a pressure-generating chamber that communicates with a nozzle opening and a piezoelectric element. The piezoelectric element includes a first electrode; a piezoelectric body layer formed on the first electrode; and a second electrode formed on the piezoelectric body layer on a side opposite the first electrode. In the liquid-ejecting head, the piezoelectric body layer has a perovskite structure and an insulating property, and an A-site and an oxygen site of the perovskite structure respectively include a vacancy formed by losing an A-site metal and a vacancy formed by losing an oxygen atom, each of the vacancies including a hydrogen atom.
