ABSTRACT:
Disclosed is an aluminum building material which comprises a substrate made of aluminum or an aluminum alloy, an anodic oxide film formed on the surface of the substrate, and a thin film containing a photocatalytically active semiconductor and deposited on the anodic oxide film. The film containing the photocatalytically active semiconductor embraces both a film formed solely of the semiconductor mentioned above and a film having fine particles of the semiconductor incorporated in or deposited on a suitable carrier such as, for example, a coating film. A fixture unit is also provided which comprises a frame member made of the aluminum building material mentioned above, a panel member having the surface thereof coated with a film containing a photocatalytically active semiconductor, and a watertight and airtight member containing fine particles of a photocatalytically active semiconductor.
