Abstract
A near-infrared cut filter includes a transparent substrate having a first and a second surfaces, opposite to each other; and a dielectric multilayer film disposed on a side of the first surface. The dielectric multilayer film reflects light within a wavelength range of 700-750 nm. A mean regular transmittance Twithin a wavelength range of 700-750 nm measured when light is incident in the normal direction from the side of the second surface is 20% or less. A mean regular transmittance Twithin a wavelength range of 600-680 nm measured when light is incident in the normal direction from the side of the second surface is 65% or more. A mean regular reflectance Rwithin a wavelength range of 700-750 nm measured when light is incident at an angle of 5° with respect to the normal direction from the side of the second surface is 80% or less.
