Abstract
The present invention provides a piezoelectric thin film comprising an electrode film with a (001) orientation, a (NaBi)TiO—BaTiOfilm with a (001) orientation (x represents not less than 0.29 and not more than 0.4) and a (Na,Bi)TiO—BaTiOpiezoelectric layer, the electrode film, the (NaBi)TiO—BaTiOfilm, and the (Na,Bi)TiO—BaTiOpiezoelectric layer being laminated in this order. The lead-free piezoelectric thin film of the present invention has low dielectric loss and high piezoelectric performance.
