ABSTRACT:
A coating film forming liquid containing a saccharide, and titanium oxide fine particles having peroxy groups or titanium oxide fine particles not having peroxy groups is applied onto a surface of a substrate such as glass, metal or a tile, and then heating is carried out at a high temperature, thus forming on the substrate a super-hydrophilic photocatalytic coating film that contains titanium oxide fine particles and has a water contact angle in a state in which the photocatalyst is not excited of less than 10°.
