摘要：To obtain both a design property and high sensitivity to infrared

light.SOLUTION: An optical filter includes a wavelength selectivity absorption layercontaining, in a transparent resin: one or more kinds of coloring agents absorbing visible

light; and fine particles. The wavelength selectivity absorption layer has: an average of alight transmittance, to light of a first near infrared wavelength range that is at least acontinuing wavelength range of 15 nm in a near infrared region, in a straight advancingdirection that is 80% or more; and a diffuse reflectance to light having a wavelength of532 nm that is 0.04% or more.SELECTED DRAWING: Figure 1
