Abstract:
To provide a near-infrared absorption composition capable of forming a film having excellent visible transparency and near-infrared shieldability, a cured film, a near-infrared absorption filter, a solid-state imaging device, and an infrared sensor. A near-infrared absorption composition includes a compound represented Formula (1) and a resin, the compound has a maximum absorption wavelength in a wavelength range of 750 to 830 nm in a film in a case where the film is formed using the near-infrared absorption composition, and a value obtained by dividing an absorbance at a wavelength of 555 nm by an absorbance at the maximum absorption wavelength is 0.10 or less.
