PROBLEM TO BE SOLVED: To provide a photocatalyst precoated molding material which withstands molding, is hardly peelable and can be evenly provided with photocatalysts in necessary segments when made into molded goods and a molding and fins for heat exchangers using the same. SOLUTION: This material includes a metallic base material 1 which consists of aluminum or aluminum alloy, a ground surface layer 2 which is formed on the surface of the metallic base material and consists of either of a poreless anodically oxidized film or microporoous anodically oxidized film and a photocatalyst layer 3 which is formed on this ground surface layer. Further, the structure obtained by including a lubricating layer 4 formed on the photocatalyst layer 3 is possible as well. |
