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.
