<p>A composite element which has a substrate (12) and a mixture film (14) formed on the surface thereof, wherein the mixture film (14) is comprised of a mixture of a boron oxide and a photocatalytic titanium oxide, exhibits high light transmissivity and is colorless and transparent. The composite element can be used for suppressing surface reflection or interference color, improving photocatalytic decomposition characteristics, increasing the speed of enhancing hydrophilicity, or the like.</p> |
