NOVELTY - A base material (1) with anti-glare layer comprises a base material (10) and an anti-glare layer (12) formed on the base material. The anti-glare layer contains silica-based matrix and does not contain silica microparticles or contains both silica-based matrix and silica microparticles. The number of protrusions (Np) on the surface of anti-glare layer measured using specific protrusion number measurement method, is 37 or more.    USE - Base material with anti-glare layer is used for image display apparatuses, component for filter, component for guard plates, and cover glass for solar cells.    ADVANTAGE - The base material with anti-glare layer has excellent anti-glare property, and enables highly efficient diffuse reflection of external light.    DETAILED DESCRIPTION - A base material with anti-glare layer comprises a base material and an anti-glare layer formed on the base material. The anti-glare layer contains silica-based matrix and does not contain silica microparticles or contains both silica-based matrix and silica microparticles. The number of protrusions (Np) on the surface of anti-glare layer measured using specific protrusion number measurement method, is 37 or more. In the number measuring method of convex portions, in each cross-sectional curve chart measured about three places where the surface of an anti-glare layer is arbitrary based on JIS B0601 (2001), the elevation difference with respect to the minimum cross-section height measures the number of the convex parts which have cross-sectional height of 100 nm or more and 500 mu m in length in a horizontal-axis and Np is average value of convex portion number. An INDEPENDENT CLAIM is included for manufacture of base material with anti-glare layer, which involves spraying coating liquid containing silica-based matrix precursor and dispersion medium, on the base material by spraying method, and heating the coated material, to form anti-glare layer.
