ABSTRACT:
A light-absorbing member has a substrate (101, 111) made of a material capable of absorbing light of which reflection is to be prevented, and an antireflection structure (102, 112, 303) having structural elements arranged on the surface of the curve in an array form at a period smaller than the wavelength of the light. The substrate having the shape of a curve viewed from a macroscopic viewpoint. The structural elements have a shape protruding or being recessed from a reference face corresponding to the curve of the substrate, and are arranged so that the straight lines connecting the reference face to the tips of the respective structural elements are nearly parallel to one another.
