Abstract
A resin film 10 comprising a polyimide-based polymer is disclosed. The resin film 10 has a tensile elastic modulus of 4.0 GPa or more. In a bending test where the resin film 10 is repeatedly folded into a U-shape until the distance between the resin film faces opposed to each other reaches 3 mm, and unfolded, the number of times of folding the resin film 10 until the resin film 10 fractures is more than 100000.
