Abstract
A transparent layered product in which the ratio of a refractive-index transition layer at the surface of a coating film is set to be a suitable ratio for increasing light transmittance is provided. In a coating film with a rough surface formed on a glass sheet, the thickness of a transition layer in which the refractive index varies continuously in its thickness direction is set to be in a range between 13% and 65% of the thickness of a layer having a substantially constant refractive index in the coating film.
