Abstract:
An infrared shielding film includes a laminated body including a high refractive index layer and a low refractive index layer, the high refractive index layer and the low refractive index layer being alternately laminated and including a high refractive index material and a low refractive index material, respectively, and the high refractive index material and the low refractive index material having mutually different refractive indexes. The infrared film also includes a primary reflection unit providing a primary reflection band with reflectivity exceeding 60% in near-infrared region in reflection spectra of the infrared shielding film for incident light angles of 0° and 60°. In a short-wavelength side of the primary reflection band, wavelengths exhibiting 70% reflectivity of the peak value in the primary reflection band are referred to as s(0) nm and s(60) nm, respectively, a relationship s(60) nm>700 nm is satisfied.
