摘要：
[Problem] An object of the present invention is to obtain a near-infrared reflective film that is low-cost, that can be produced with a large area, in which, in the optical properties, interference unevenness is particularly small, and which has excellent film physical properties.[Solving Means] Provided is a near-infrared reflective film composed of a lamination unit including: a high refractive layer containing a first metal oxide particle and a first water-soluble polymer, a low refractive layer containing a second metal oxide particle and a second water-soluble polymer and a mixed layer located between the high refractive layer and the low refractive layer and which contains the first metal oxide particle, the second metal oxide particle and a third water-soluble polymer, wherein the refractive index of the low refractive layer is smaller than the refractive index of the high refractive layer by 0.1 or more, and the first metal oxide particle and the second metal oxide particle have different metal oxides.
