Zusammenfassung:A piezoelectric element includes a first electrode; a seed layer comprised of a composite oxide having a perovskite structure and preferentially oriented to a (100) plane, the seed layer including bismuth in an A site and including iron and titanium in a B site, the seed layer having a thickness of less than 20 nm; a piezoelectric layer provided on the seed layer, the piezoelectric layer consisting of a piezoelectric material having a perovskite structure and preferentially oriented to a (100) plane; and a second electrode provided on the piezoelectric layer.
