Abstract:
An optical element is provided that includes a base having a smooth surface and a rough surface on one surface thereof, an antireflection film having an irregularity structure on a surface of the antireflection film over the smooth surface of the base, and a light shielding film over the rough surface, wherein the irregularity structure of the antireflection film has an average height of 50 nm or less in an overlapping portion, in which an edge portion of the antireflection film and an edge portion of the light shielding film overlap each other over the smooth surface.

Claim (Index 1):
An optical element comprising:\n a base having, on at least one surface, a smooth surface and a rough surface surrounding an outer periphery of the smooth surface; an antireflection film continuously formed over the smooth surface and over a portion of the rough surface of the base, the antireflection film having an irregularity structure on a surface opposite the base; and a light shielding film continuously formed over at least the rough surface and a portion of the smooth surface to cover an outer peripheral edge portion of the antireflection film, wherein the irregularity structure has an average height in a range from 10 nm to 50 nm in a region where the antireflection film and the light shielding film overlap each other over the smooth surface.
