Zusammenfassung:PROBLEM TO BE SOLVED: To provide an optical body capable of improving the antireflection characteristic even when a wave surface having a wavelength of a wavelength of visible light or less includes a concaved curve surface between a peak and a bottom.SOLUTION: The optical body having an antireflection function has a wave surface having a wavelength of a wavelength of visible light or less. The wave surface has a concaved curve surface between a peak and a bottom. The inflection point of the area of the cross section obtained by cutting with a plane perpendicular to the vibration direction of the wave surface is located closer to the bottom of the wave surface than to the center of the vibration.
