An optical filter (1a) includes a light-absorbing layer (10). The light-absorbing layer absorbs light in at least a portion of the near-infrared region. When light with a wavelength of 300 nm to 1200 nm is incident on the optical filter (1a) at incident angles of 0°, 30°, and 40°, the optical filter (1a) satisfies given transmittance requirements. IEθ1/θ2CR, IEθ1/θ2CG, and IEθ1/θ2CB defined for two incident angles θ1° and θ2° (θ1
