NOVELTY - A solar cell cover (100) is obtained by laminating translucent substrate (102), heat-generating layer having transparent conductive film (104) and photocatalytic thin film (106). The photocatalytic thin film is formed by sputtering target source material in film-forming region, contacting and reacting reactive gas and sputtered material in a reaction region, moving translucent substrate to film-forming region and reaction region to repeatedly carry out sputtering and reaction processes, and contacting obtained thin film (b) with plasma.    USE - Cover is used for solar cell. Uses include but are not limited to building material, window frame, dustproof cover, reflecting plate, sound insulation wall, light source cover, outdoor display board, illuminating lamp for vehicles, roof material and household appliance.    ADVANTAGE - The solar cell cover has excellent photocatalytic characteristics.    DETAILED DESCRIPTION - A solar cell cover is obtained by laminating a translucent substrate, a heat-generating layer having a transparent conductive film and a photocatalytic thin film on photocatalytic thin film. The photocatalytic thin film is formed by sputtering target source material containing titanium metal in film-forming region of a vacuum vessel and adhering titanium to surface of heat-generating layer, contacting and reacting reactive gas comprising source material and the sputtered material in a reaction region, moving translucent substrate with heat-generating layer to film-forming region and reaction region to repeatedly carry out sputtering process and reaction process to deposit thin film (a) and thin film (b), and contacting thin film (b) with plasma comprising mixed gas formed by mixing inert gas actively at same flow volume of reactive gas and reactive gas. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of solar cell cover; and    (2) snow melting method.    DESCRIPTION OF DRAWING(S) - The drawing shows the sectional view of the solar cell cover.
