PHOTOCATALYST COATED BODY

The present invention provides a photocatalyst coated body which can realize a sufficient photocatalytic activity and adhesiveness with a substrate, without significantly impairing an appearance of a substrate, especially an exterior building material. The photocatalyst coated body has a structure including a substrate, an intermediate layer formed on the substrate, and a photocatalyst layer formed on the intermediate layer. The intermediate layer includes inorganic oxide particles having an average particle diameter of nanosize. The photocatalyst layer includes photocatalyst particles having an average particle diameter of more than 0 micron to less than 10 microns and inorganic oxide particles having an average particle diameter of nanosize. A sum of a film thickness of the intermediate layer and a film thickness of the photocatalyst layer is 0.3 microns or more to 1.5 microns or less. 本发明在于提供对基材、尤其是外装用建材的外观不会有大的损伤，且可实现充分的光触媒活性以及与基材的密着性的光触媒涂装体。具体而言，其具备基材、设置于该基材上的中间层以及设置于该中间层上的光触媒层的结构。所述中间层包含平均粒径为纳米尺寸的无机氧化物粒
