ABSTRACT:
A polyimide film having a polyimide as the primary constituent and containing at least a polymeric electroconductive material, whereinin a weight-decrease vs. temperature-increase curve when the polyimide film is heated gradually from 30° C., a weight-decrease rate at a first inflection point, where an amount of difference in weight-decrease rates decreases first from 30° C., is in the range of −1.9% or more and −1.4% or less.
