摘要

Disclosed is a piezoelectric film which comprises a (001)-oriented NaxLa1-xNiO3-x layer and a (001)-oriented (Na, Bi)TiO3-BaTiO3 layer, wherein x is 0.01-0.1 (inclusive). The NaxLa1-xNiO3-x layer (0.01 = x = 0.1) and the (Na, Bi)TiO3-BaTiO3 layer are laminated. The piezoelectric film contains a lead-free ferroelectric material and has low dielectric loss and high piezoelectric performance equivalent to that of PZT. Also disclosed is a method for producing the piezoelectric film.
