Abstract
A composition includes: a coloring material that allows transmission of infrared light and shields visible light; an infrared absorber; and a resin, in which the infrared absorber includes a compound having an absorption maximum in a wavelength range of longer than 900 nm and 1000 nm or shorter, and a ratio A/B of a minimum value A of an absorbance of the composition in a wavelength range of 400 to 950 nm to a maximum value B of an absorbance of the composition in a wavelength range of 1100 to 1300 nm is 4.5 or higher.
