The present invention pertains to an optical filter comprising: an absorption layer containing a near-infrared-absorbing pigment and a transparent resin; and a reflection layer, wherein the transparent resin has a maximum absorption wavelength of 760-900 nm, an average transmittance T435-480aveTR at 435-480 nm of at least 90%, and an average transmittance T480-590aveTR at 480-590 nm of at least 90%, the dichloromethane has a maximum absorption wavelength of 760-900 nm, an average transmittance T435-480aveDCM at 435-480 nm of at least 95%, and an average transmittance T480-590aveDCM at 480-590 nm of at least 97%, the difference between T435-480aveDCM and T435-480aveTR is 10.5% or less, the difference between T480-590aveDCM and T480-590aveTR is 10.5% or less, and the average transmittance of the optical filter at 800-900 nm and an incident angle of 60 degrees is 5% or less. |
