摘要：
It is an object of the present invention to provide a lead-free piezoelectric film including a lead-free ferroelectric material and having low dielectric loss and high piezoelectric performance comparable to that of PZT, and a method of manufacturing the lead-free piezoelectric film.The present invention is directed to a piezoelectric film comprising a (NaxBiy)TiO0.5x+1.5y+2—BaTiO3 layer with a (110) orientation, where 0.30≦x≦0. 46 and 0.51≦y≦0.62.
