PROBLEM TO BE SOLVED: To provide a functional film which brings high corrosion resistance to an aluminum-based material, is environmentally friendly, and has an excellent action of decomposing hydrogen peroxide and removing harmful gases such as carbon monoxide, chlorine and sulfurous acid, and It is an object of the present invention to provide an aluminum-based material having the functional film. A method for producing a functional film by forming a boehmite film or an aluminum hydroxide film on an aluminum-based material and immobilizing a metal oxide having an oxidation catalyst ability on the surface of the film, and the functionality An aluminum-based material having a film is used.
