PROBLEM TO BE SOLVED: To provide a building material in which the surface of a base material is provided with an ultraviolet radiation preventive layer containing zinc oxide, provided with the ultraviolet radiation preventive layer not decomposing a base material and an intermediate resin layer by an optical radical generable from the zinc oxide, thus excellent in durability, and a method for producing the same.SOLUTION: Provided is a building material 10, 20 in which an ultraviolet radiation preventive layer 2 containing zinc oxide particles 3 and silica particles 4 is formed on the surface of a base material 1 directly or indirectly via an intermediate resin layer 7, and the silica particles 4 are fixed to the base material 1 or the intermediate resin layer 7. |
