Abstract: Provided is an infrared cut filter including: an infrared absorbing layer of a transparent resin containing an infrared absorber; and a selected wavelength cut layer stacked on the infrared absorbing layer, wherein the following requirements are satisfied. (i) In a spectral transmittance curve for an incident angle of 0°, an average transmittance in a 450-600 nm range is 80% or more, a transmittance in a 700-1200 nm range is 2.0% or less, and D0 represented by the following expression is less than 0.04. D0 (%/nm)=(Tmax·0−Tmin·0)/(λ(Tmax·0)−λ(Tmin·0)) (ii) wherein a spectrum transmittance curve for an incident angle of 30°, an average transmittance in the 450 to 600 nm range is 80% or more, a transmittance in the 700-1200 nm range is 2.0% or less, and D30 represented by the following expression is less than 0.04. D30 (%/nm)=(Tmax·30−Tmin·30)/(λ(Tmax·30)−×(Tmin·30))
