Abstract: A photosensitive coloring composition for an infrared pass filter contains a colorant, a polymerizable compound, a photopolymerization initiator, and a polymerization inhibitor. The polymerizable compound contains a first (meth)acrylate with two or more functional groups, at least one of the two or more functional groups being an amino group. A percentage of a mass of the first (meth)acrylate relative to a mass of the photopolymerization initiator is 50% or greater and 500% or less. A percentage of a mass of the polymerization inhibitor relative to a mass of the photopolymerization initiator is 3% or greater and 30% or less.

Abstract: An infrared light pass filter includes a colorant, an indium tin oxide, and a polymer. The infrared light pass filter has an average transmittance of 30% or less in a first wavelength range of 400 nm or greater and 800 nm or less, an average transmittance of 75% or more in a second wavelength range of 900 nm or greater and 1100 nm or less, and an average transmittance of 55% or less in a third wavelength range of 1300 nm or greater and 2500 nm or less.
