摘要：
An antireflective structure having a higher antireflective effect compared with those of conventional antireflective structures is produced by a simple process. The antireflective structure (10) includes a plurality of concavities (2a) each having a plurality of convexities (1a) thereon, and a pitch between the plurality of convexities (1a) and a pitch between the plurality of concavities (2a) are smaller than a wavelength of light incident to the antireflective structure (10).
