Optical member and method for manufacturing same

Abstract

An optical component capable of sufficiently suppressing a reflection even if the incident angle of a light source changes with a line direction being as a rotation axis in a reflection suppressing structure in a line-and-space shape. The optical component includes a base having a function as an optical component, and a reflection suppressing structure in a line-and-space shape formed on a surface of the base, and including a plurality of sequential concavities and convexities defining a convex shape in a cross-sectional view. When a position of a mid-point of a bottom side of the convex shape is an origin, the bottom side is y-axis, a height direction relative to the bottom side is x-axis, a width of the bottom side of the convex shape is P, a height of the convex shape is H, r=0.1, and an arbitrary position on the convex shape is (x, y), the convex shape satisfies a following formula (1): - P 2  ( 1 - r H  x - 1 ) 2 ≦ y ≦ P 2  ( 1 - r H  x - 1 ) 2 Formula   ( 1 )
