摘要： The aromatic diamine compound of the present invention is represented by the following formula (1), and from the aromatic diamine compound a polyimide having a repeating unit represented by the following formula (4), which has low-temperature adherability, can be obtained. In the formulas (1) and (4), n is an integer of 3 to 7, each R is independently an atom or a group selected from the group consisting of a hydrogen atom, a halogen atom and a hydrocarbon group, the same or different two hetero atoms selected from nitrogen atoms and oxygen atoms bonded to each benzene ring are at the ortho- or meta-positions to each other on at least one benzene ring, and when n is 3, the hetero atoms are at the ortho- or meta-positions to each other on all the benzene rings. In the formula (4), Y is a tetravalent organic group.
