Near-infrared reflective film and near-infrared reflector provided with the same

A near-infrared reflective film having

• a constitution in which, on a base material, high refractive layers and low refractive layers are alternately laminated individually to form at least two units,
• wherein each of said units consists of one of said high refractive layers and one of said low refractive layers, each of said high refractive layers containing a water-soluble polymer and a metal oxide particle having a refractive index higher than the refractive index of the water-soluble polymer and each of said low refractive layers containing a water-soluble polymer and a metal oxide particle having a refractive index lower than the refractive index of the water-soluble polymer,
• wherein a transmittance of the film in a visible light region according to JIS R3106-1998 is 50% or higher,
• wherein each of the high refractive layers and the low refractive layers has a thickness of 20 nm or more,
• wherein the total number of the layers of the high refractive layers and the low refractive layers is n, the total film thickness of the component layers from the region of n/2 to the base material is Σd1, the total film thickness of the component layers from the region of n/2 to the outermost layer is Σd2, and the film thickness ratio Σd1/Σd2 is from 1.20 to 1.40, and
• wherein a total film thickness of the high refractive layers from the region of n/2 to the base material is greater than a total film thickness of the high refractive layers from the region of n/2 to the outermost layer.
