Abstract
A photocatalytic sheet which has a base made of polymeric organic compound, that is not decomposed by a photocatalytic function, and also hardly loses the photocatalytic function after washing and is capable of providing the photocatalytic function even in an environment without sufficient ultraviolet radiation from outside. Using a fiber, a filament, a yarn made of fibers or filaments, a ribbon, a knitted fabric, a woven fabric, a nonwoven fabric, or a film as the base, a base protective layer is formed on a part of the base, which is made of the polymeric organic compound, and a photocatalytic semiconductor layer is formed on the entire surface of the base including the base protective layer.
