Abstract
A resin filmcomprising a polyimide-based polymer is disclosed. The resin filmhas a tensile elastic modulus of 4.0 GPa or more. In a bending test where the resin filmis 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 filmuntil the resin filmfractures is more than 100000.
