PROBLEM TO BE SOLVED: To provide a near-infrared absorption film and a near-infrared absorption filter excellent in durability while maintaining a near-infrared blocking effect and visible light transmittance in a broad wavelength region. SOLUTION: The near-infrared absorption film is obtained by laminating, on a transparent base film, a near-infrared absorption layer comprising a composition containing a transparent resin and one or more near-infrared absorbing dyes having maximum absorption at a wavelength of 800-1,100 nm, wherein one of the near-infrared absorbing dyes is an aromatic diimmonium compound having bis(trifluoromethanesulfonyl)imidic acid as a counter anion.
