PROBLEM TO BE SOLVED: To provide a new diamine compound giving a material excellent in low water-absorbing ability, dimensional stability and the like; a polyimide material produced by using the same; and a film made of the same. SOLUTION: A polyimide material includes a polyamic acid and/or polyimide obtained by reaction of a new aromatic diamine compound of formula (1)(wherein R<SP>1</SP>-R<SP>12</SP>each independently represents hydrogen, halogen, hydroxy, hydrocarbon, halogenated hydrocarbon or alkoxy, R<SP>13</SP>-R<SP>16</SP>each independently represents hydrogen, halogen, hydroxy, hydrocarbon, halogenated hydrocarbon or alkoxy, n is an integer of 0-2) with a tetracarboxylic acid dianhydride or a reactive derivative thereof, i.e. an acyl compound.
