Abstract

Provided is a method for producing a piezoelectric thin-film element including a piezoelectric thin-film layer having good surface morphology and high crystallinity. The method includes forming a lower electrode layer on a substrate; forming a piezoelectric thin-film buffer layer on the lower electrode layer at a relatively low film-formation temperature; forming a piezoelectric thin-film layer on the piezoelectric thin-film buffer layer at a film-formation temperature that is higher than the film-formation temperature for the piezoelectric thin-film buffer layer; and forming an upper electrode layer on the piezoelectric thin-film layer.
