PROBLEM TO BE SOLVED: To provide an aluminum fin material suitable to the indoor equipment of an air conditioner and almost free from degradation in hydrophilicity.SOLUTION: The aluminum fin material of the invention comprises: a base plate made of aluminum; a first functional film formed on the base plate; and a second functional film formed on the surface of the first functional film, and when n-tetradecane is dropped on the surface, the contact angle is 15° or more while water is dropped, the contact angle is less than 50°. In the aluminum fin material, at least one of the first functional film and the second functional film contains a hydrophilic resin having at least one group in the structure selected from the group consisting of a hydroxyl group, a carboxyl group, a sulfonic acid group and a polyether group, with a quantity of adhesion of 0.05 to 5 g/mwhile at least the other contains a silicone component with a quantity of adhesion of 0.001 to 1 g/m. |
