This optical filter (1a) is provided with a light-absorption layer (10). The light-absorption layer absorbs at least part of the light in the near infrared region. The optical filter (1a) satisfies predetermined conditions with respect to transmissivity when light having a wavelength of 300 nm to 1200 nm is incident upon the optical filter at incident angles of 0°, 30° and 40°. In addition, IEθ1 /θ 2 λ1 to λ2, IAEθ1/θ2 λ 1 to λ2 and ISEθ1/θ2 λ 1 to λ 2, which are defined by formulae (1) to (3) in the range of a predetermined wavelength λ, satisfy predetermined conditions for two incident angles θ1° and θ2° (where θ1 < θ2) selected from 0°, 30° and 40°.
