| 摘要 |
A photocatalyst sheet whose substrate made of an organic polymer compound is not decomposed by a photocatalytic function, whose photocatalytic function is not lost even when washed, and which can provide a photocatalytic function even under an environment in which sufficient ultra-violet rays cannot be obtained from the outside. Fibers, filament fibers, or yarns, ribbons, knitted fabrics, woven fabrics or non-woven fabrics made of filaments, or films, are used as the substrate. A substrate protective layer is formed at a portion, made of an organic polymer compound, of the substrate, and a layer of a photocatalytic semiconductor is formed on the entire surface of the substrate inclusive of the substrate protective layer. |
