SURFACE TREATED METAL AND METHOD FOR PRODUCING THE SAME. The present invention relates to surface-treated metal including a metal, and a coating material that is formed on a surface of the metal, wherein an outermost layer 3a of the coating material is a photocatalytic film containing the particles that exhibit a photocatalytic activity and an organic-inorganic composite resin, in a volume ratio of particles that exhibit a photocatalytic activity for the photocatalytic film which is in a range of 0.5% by volume to 50% by volume, the resin of the organic-inorganic composite contains a siloxane linkage and at least one group selected from the group consisting of an aryl group, a carboxyl group, an amino group, a hydroxyl group, and an alkyl group having 1 to 12 carbon atoms. carbon, the coated material has concave shapes on a surface thereof, on the side of the outermost layer 3a, an area of the outermost layer 3a is 50% to 98% of an area of a surface of the metal, which When the coating material is seen in plan view, and a surface area of the outermost layer 3a is from 101% to 5000% of the surface area of the metal. |
