Abstract
A titanium dioxide film () having at least photocatalytic activity, whose light linear transmittance corresponding to light having a wavelength of 550 nm is not less than 50% and whose thickness is 0.1 to 5 μm or so, is formed on a transparent substrate () constituted by a glass plate or the like. Preferably, a precoat film (), which has optical transmissivity and is constituted by a SiOfilm having a thickness of 0.02 to 0.2 μm or so, is provided between the transparent substrate () and the titanium dioxide film (). Thereby, excellent photocatalytic action and optical transmissivity can be obtained. Moreover, members composing various structures such as a glass window, which are especially required to have optical transparency, can be further provided with photocatalytic activities.
