Abstract
In a transparent layered product in which a coating film having a surface with roughness is formed on a glass sheet, the reflectance of the transparent layered product is decreased by controlling the refractive index distribution in a transition layer produced by the roughness. In the transition layer present at the surface of the coating film, in which the refractive index varies continuously in its thickness direction, the variation in refractive index in the thickness direction was indicated by a convex curve over the whole area of the transition layer, when the variation is shown on a plane defined by a horizontal axis indicating a refractive index and the vertical axis indicating the thickness direction of the transition layer, with the glass sheet positioned on the lower side.
