Abstract:
A piezoelectric element includes a substrate, and a lower electrode, a piezoelectric film, an adhesion layer, and an upper electrode provided on the substrate in this order, in which the piezoelectric film has a perovskite structure that is preferentially oriented to a (100) plane and is a composite oxide represented by the compositional formula Pb[(Zr x Ti 1-x ) 1-y Nb y ]O 3 , where x satisfies 0<x<1 and y satisfies 0.10≤y<0.13, I (200) /I (100) , which is a ratio between a diffraction peak intensity I (100)  from the perovskite plane and a diffraction peak intensity I (200)  from a perovskite plane as measured by X-ray diffraction method, satisfies 0.85≤I (200) /I (100) ≤1.00, and the adhesion layer contains a metal having an ionization energy of 0.34 eV or less.
