[PROBLEMS] A near-infrared reflective film that uses a water-based coating solution for forming a refractive index, is low in manufacturing cost, can be increased in area, has high near-infrared reflectance and high visible light transmittance, and has excellent durability. And a near-infrared reflector provided with a near-infrared reflective film. In a near-infrared reflective film having at least one unit composed of a high refractive index layer and a low refractive index layer on a substrate, at least one of the high refractive index layer and the low refractive index layer comprises: A near-infrared reflective film comprising metal oxide particles having a volume average particle diameter of 100 nm or less, a lithium compound, and a water-soluble polymer.
