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 6):
A method for manufacturing an optical element, the method comprising:\n preparing a base having, on at least one surface, a smooth surface and a rough surface surrounding an outer periphery of the smooth surface; continuously forming, over the smooth surface and over a portion of the rough surface, an antireflection film having an irregularity structure on a surface of the antireflection film; applying a light shielding coating material on at least the rough surface and a portion of the smooth surface to cover an outer peripheral edge portion of the antireflection film; and bringing into contact an elastic member with the light shielding coating material applied on the antireflection film over the smooth surface to arrange for the irregularity structure to have an average height of 50 nm or less.
