PROBLEM TO BE SOLVED: To provide a polyimide film that is resistant to the degeneration of the film and/or characteristic deterioration due to hydrolysis even when immersed in an alkali solution and is thin with a thickness of 1.0-10.0 μm.SOLUTION: When an L value of a polyimide film with a thickness of 1.0-10.0 μm is 28-45, and a molecular weight of a repeating unit of a polyimide is 100%, the imide group has a molecular weight of 40% or less.SELECTED DRAWING: None |
