Abstract
An object is to provide a fluorine-containing polymer film. The object can be achieved by a fluorine-containing polymer film having a thermal shrinkage of 0.4% or less after being heated at 90° C. for 1 hour, and having a relative permittivity of 3 to 50 at 25° C. at 1000 Hz, or a fluorine-containing polymer film having a crystallinity of 50% or more and an elongation at break of 400% or more.
