Abstract
An optical window member includes a transparent synthetic resin plate having a surface with a protruding/recessed pattern of a predetermined fineness that causes light diffusion, and an optical thin film formed on the surface of the transparent synthetic resin plate with the protruding/recessed pattern. The optical thin film determines a component of light transmitted through the optical thin film and light reflected from the optical thin film.
