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 ( 1 b) comprises a substrate ( 2 ) such as fiber and coated layers ( 3 ) on both sides of the substrate ( 2 ), and the coated layer ( 3 ) constitutes the photocatalyst-containing layer in which apatite-coated photocatalyst particles ( 4 ) are dispersed and fixed with resin. Here, the coated photocatalyst particles ( 4 ) 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 ( 1 b) are mutually welded, the photocatalyst-containing layer of each photocatalyst sheet ( 1 b) is not removed, and its surface is mutually held, and welded together by thermal welding or others.
