Abstract
A resin film formed of a resin containing a polymer containing an alicyclic structure and having crystallizability, wherein a crystallization degree of the polymer is 30% or more, and a thickness variation Tv of the resin film represented by the following formula (1) is 5% or less. The formula (1) is Tv [%]=[(Tmax−Tmin)/Tave]×100. In the formula (1), Tmax is a maximum value of the thickness of the resin film, Tmin is a minimum value of the thickness of the resin film, and Tave is an average value of the thickness of the resin film).
