Original Abstract Submitted

Provided is a piezoelectric film which is capable of suppressing a decrease in acoustic characteristics associated with use of a long period of time and has high durability. The piezoelectric film includes a piezoelectric layer consisting of a polymer-based piezoelectric composite material which contains piezoelectric particles in a matrix containing a polymer material and electrode layers formed on both surfaces of the piezoelectric layer, in which, in a case where a smaller value of a domain ratio X between a c domain and an a domain, which is measured by an X-ray diffraction method from one main surface side of the piezoelectric layer, or a domain ratio Y between a c domain and an a domain, which is measured by an X-ray diffraction method from the other main surface side of the piezoelectric layer, is set to 1.00, the other domain ratio is 1.05 or more.
