Provided is a piezoelectric film having high piezoelectric performance. The piezoelectric film is a piezoelectric film including a piezoelectric layer consisting of a polymer-based piezoelectric composite material that contains piezoelectric particles in a matrix containing a polymer material, and electrode layers formed on both surfaces of the piezoelectric layer, in which the piezoelectric particles observed in a cross section of the piezoelectric layer in a thickness direction have a circularity of 0.65 to 0.92.
