Zusammenfassung:The near-infrared reflective film is 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 that is located between the high refractive layer and the low refractive layer and contains the first metal oxide particle, the second metal oxide particle, and a third water-soluble polymer. The refractive index of the low refractive layer is smaller than the refractive index of the high refractive layer by 0.1 or more. The first metal oxide particle and the second metal oxide particle are different metal oxides.
