Abstract:
A polyimide film including a polyimide obtained by polymerizing a tetracarboxylic acid component and a diamine component. The tetracarboxylic acid component consists of one or more tetracarboxylic dianhydride (a 1 ), in which at least one of the bonds linking the two cyclic anhydride structures contained in the molecule is a freely rotatable bond and a phthalic anhydride structure is not contained therein, and one or more tetracarboxylic dianhydride (a 2 ) having an alicyclic structure, in which each of two cyclic anhydride structures shares at least one carbon-carbon bond with the alicyclic structure and a freely rotatable bond is not contained in the molecule; and the diamine component includes one or more diamine having a 9,9-diphenylfluorene structure in an amount of 5 to 50 mol %.

Claim (Index 9):
The polyimide film according to  claim 6 , wherein the tetracarboxylic dianhydride (a 2 ) is a compound selected from 1,2,3,4-cyclobutane tetracarboxylic dianhydride, 1,2,4,5-cyclohexane tetracarboxylic dianhydride, norbornane-2-spiro-\u03b1-cyclopentanone-\u03b1\u2032-spiro-2\u2033-norbornane-5,5\u2033,6,6\u2033-tetracarboxylic dianhydride, and decahydro-1,4:5,8-dimethanonaphthalene-2,3,6,7-tetracarboxylic dianhydride.
