Abstract: An antireflection film including an optical element, formed on an optical surface of an optical member, and is configured to prevent a reflection of a light beam incident on the optical surface, wherein a maximum reflectance P1 in a first wavelength region and a maximum reflectance P2 in a second wavelength region at a wavelength side longer than the first wavelength region, satisfies a relation of P1>P2, as a spectral reflectance property when a light beam is incident on the optical surface at an incident angle of 0 degree; and by shifting a wavelength range where the reflectance is a specific value or less, to a wavelength side longer than the second wavelength region, the reflectance in the second wavelength region is decreased, and the reflectance in the first wavelength region is increased so that a luminance difference is small between a ghost in the first wavelength region and a ghost in the second wavelength region.
