A resin film, which is a resin film made of a resin containing a polymer, wherein the polymer contains an alicyclic structure and has crystallinity, the crystallinity of the polymer is 30% or more, and the formula of the resin film ( 1) The thickness unevenness Tv shown is 5% or less. Here, the above formula (1) is Tv[%]=[(Tmax-Tmin)/Tave]×100, in this formula (1), Tmax is the maximum value of the thickness of the aforementioned resin film, and Tmin is the value of the aforementioned resin film The minimum value of the thickness, and Tave is the average value of the thickness of the aforementioned resin film. |
