The purpose of the present invention is to provide a piezoelectric film having high transparency (especially, haze value), formal and visual uniformities, and highly uniform polarizability.nThe present invention provides a piezoelectric film of which the total light transmittance is 90% or more, the total haze value is 4.0% or less, and the coefficient of variation in thickness when the thickness is measured in 10 places per square centimeter over the entire region in a planar direction is 10% or less. |
