An anti-reflection sheet is formed in a manner of forming a resin layer, which has many fine projections 12, on a flat and smooth surface of a transparent substrate 11. Transparent resin is molded into the projections 12, the projections 12 have an almost quadratic function-shaped cross section including a center axis C perpendicular to the surface of the substrate 11, and a surface of the projection 12 is preferably a rotational paraboloid. A ratio (aspect ratio) b/a of a height b and width a of the projection 12 is 1 or less. Additionally, an arranged pitch P of the projections 12 is not more than half of a wavelength of incident light.
