Beschreibung
Zusammenfassung:	The purpose of the present invention is to obtain a near-infrared reflective film which can be produced to have a large area at low cost and has excellent film properties and optical characteristics, in particular, reduced interference irregularity. [Solution] A near-infrared reflective film which comprises a layered unit having a high refraction layer that contains first metal oxide particles and a first water-soluble polymer, a low refraction layer that contains second metal oxide particles and a second water-soluble polymer, and a mingled layer that is positioned between the high refraction layer and the low refraction layer and contains the first metal oxide particles, the second metal oxide particles and a third water-soluble polymer. The refractive index of the low refraction layer is lower than the refractive index of the high refraction layer by 0.1 or more, and the first metal oxide particles and the second metal oxide particles are composed of different metal oxides.
