摘要

Provided is a piezoelectric thin film that contains a lead-free ferroelectric material and has high piezoelectric performance comparable to lead zirconate titanate (PZT). Also provided is a manufacturing method for said piezoelectric thin film. The piezoelectric thin film is provided with a (001)-oriented LaNiO3 film, a (001)-oriented NaNbO3 film, and a (001)-oriented (Bi, Na, Ba)TiO3 film, layered in that order.
