    Abstract: Disclosed is use of a composite material including a transparent photocatalyst layer that can allow a design of a substrate to be utilized and, at the same time, can exert a photocatalytic decomposition function while effectively suppressing a silicone contamination-derived appearance change over a long period of time. The composite material includes a photocatalyst layer. The photocatalyst layer includes photocatalyst particles and inorganic oxide particles where the total mass of the photocatalyst particles and the inorganic oxide particles is 80% by mass (exclusive) to 100% by mass (inclusive) when the mass of the whole photocatalyst layer is presumed to be 100% by mass. The number mean particle diameter of particulate components constituting the photocatalyst layer is less than 90 nm as calculated by measuring the length of any 100 particles present in a field of view under a scanning electron microscope at a magnification of 200000 times. The photocatalyst layer is transparent and has a thickness of not more than 3 µm. The photocatalyst is excited by sunlight to decompose substances, thereby reducing or preventing silicone contamination on the surface of the photocatalyst layer.
