PROBLEM TO BE SOLVED: To provide an aluminum fin material for a heat exchanger preventing limitation of selection of a resin type forming a resin film layer, preventing generation of uncomfortable smell due to mold and bacteria and having a high remaining ratio of an antibacterial and antifungal agent after film formation.SOLUTION: The aluminum fin material 1 for the heat exchanger includes a substrate 2 comprising aluminum or aluminum alloy and at least one resin film layer 3 formed on the surface of the substrate 2, and the antibacterial and antifungal agent is included in the resin film layer 3. The antibacterial and antifungal agent comprises plating pulverized pieces. The average particle diameter of the plating pulverized pieces is set to be the film thickness of the resin film layer 3 or less, and 0.1-50 mass% of the plating pulverized pieces is included in the resin film layer 3. |
