Provided is an aluminum fin material in which the hydrophilicity of a fin material surface is sustained for a long period time. A fin material (10A) having a hydrophilic film layer (2) and a lubricant film layer (3) provided to the surface of an aluminum plate (1) in the stated order, the fin material being characterized in that: the hydrophilic film layer (2) is composed of a polymer configured solely from a monomer having a carboxyl group, a copolymer containing a monomer having a carboxyl group, or a resin substance containing a hydrophilic resin as a mixture thereof; and the lubricant film layer (3) is composed of a resin composition in which a crosslinking agent (6) has a solids ratio of 0.2 to 70 mass%, the lubricant film layer (3) containing one or more lubricant resins selected from the group consisting of polyethylene glycol, carboxymethyl cellulose, and an alkali metal salt of carboxymethyl cellulose, and one or more crosslinking agents (6) selected from the group consisting of a water-soluble epoxy resin, a water-soluble carbodiimide compound, a water-dispersible carbodiimide compound, and a water-soluble oxazoline group-containing resin.
