Abstract
The present invention provides the photocatalyst sheet and the methods of welding and manufacturing the same, by which the substrate and resin of the photocatalyst-containing layer are not decomposed by photocatalyst particles, mutual welding of sheets is easy, and the photo-redox effect of a photocatalyst can be obtained. A photocatalyst sheet () comprises a substrate () such as fiber and coated layers () on both sides of the substrate (), and the coated layer () constitutes the photocatalyst-containing layer in which apatite-coated photocatalyst particles () are dispersed and fixed with resin. Here, the coated photocatalyst particles () on the surface of the photocatalyst-containing layer are so fixed as to have the parts exposed from the surface of the photocatalyst-containing layer. In case that photocatalyst sheets () are mutually welded, the photocatalyst-containing layer of each photocatalyst sheet () is not removed, and its surface is mutually held, and welded together by thermal welding or others.
