摘要:
A piezoelectric element includes a piezoelectric layer, and an electrode provided on the piezoelectric layer. The piezoelectric layer is composed of a compound oxide having a perovskite structure and containing bismuth lanthanum ferrate manganate and barium titanate. The molar ratio of the barium titanate to the total amount of the bismuth lanthanum ferrate manganate and the barium titanate is 0.09 or more and 0.29 or less. A liquid ejecting head includes a pressure-generating chamber communicating with a nozzle opening, and a piezoelectric element as described above. A liquid ejecting apparatus includes the above-described liquid ejecting head.
