PROBLEM TO BE SOLVED: To make it possible to obtain a photocatalyst effect without impairing transparency and to improve UV absorptivity and water repellence by forming titanium dioxide thin films on at least one surfaces of transparent members. SOLUTION: At least one surfaces of the transparent members 1a, 1b are provided with the amorphous titanium dioxide thin films 2 of <=0.5μm thickness and, if necessary, metallic thin films 2a and means 3 for removing water drops sticking to the transparent members 1a, 1b by air blow. As a result, the photocatalyst effect is obtd. and UV rays harmful to the human body are absorbed without impairing the transparency. The photocatalyst effect is more effectively exhibited by the absorbed UV rays.
