Abstract
An object of the present invention is to provide a matted object capable of achieving both a lower range of glossiness and an antifouling property. A matted object includes a substrate, and a glassy layer provided on the surface of the substrate. The surface of the glassy layer has a 60°-glossiness of 20 or less, a skewness Rsk of −0.5 or more, and a maximum height roughness Rz more than 2.5 μm and less than 5.7 μm, the skewness Rsk and the maximum height roughness Rz being specified in JIS B0601 (2001).
