Abstract

A polyimide film is characterized in that is obtained by block copolymerizing an aromatic diamine component consisting of 10~25 mol% of para-phenylene diamine (a1) and 75~90 mol % of 4, 4' -diaminodiphenyl ether (a2) with an aromatic tetracarboxy acid consisting of 75~99.9 mol % of pyromellitic acid and 0.1~25 mol% of 3, 3', 4,4' -biphenyltetracarboxy acid; and the Young's modulus, linear expansion coefficient, water absorbency, and glass transition temperature of said polyimide film are controlled in a specific range.
