Abstract
An infrared-cut filter () includes a near-infrared reflecting film () and an absorbing film (). The near-infrared reflecting film () and the absorbing film () have the following features (A) to (E); (A) 700 nm≤λ(0°, 70%)<λ(0°, 20%)≤770 nm; (B) 650 nm≤λ(40°, 70%)<λ(40°, 20%)≤720 nm; (C) λ(40°, 20%)<λ(40°, 20%); (D) the spectral transmittance of light incident on the absorbing film () is 15% or less at λ(0°, 20%) and λ(40°, 20%); and (E) an average of the spectral transmittance of light incident on the near-infrared reflecting film () and an average of the spectral transmittance of light incident on the absorbing film () are 75% or more in the wavelength range of 450 to 600 nm.
