Abstract
Provided is a resin film having excellent size stability in a high-temperature environment. A resin film formed of a resin containing an alicyclic structure-containing polymer having crystallizability, wherein an absolute value of a thermal size change ratio when the film is heated at 150° C. for 1 hour is 1% or less in any in-plane direction of the film. The alicyclic structure-containing polymer may preferably be a hydrogenated product of a ring-opened polymer of dicyclopentadiene. Also provided is a method for producing the resin film including a step of relaxing strain of the crystallized film while the crystallized. film is kept flat.
