HEAT RAY SHIELDING FILM, HEAT RAY SHIELDING BODY USING THE FILM, AND HEAT RAY SHIELDING FILM MATERIAL

PROBLEM TO BE SOLVED: To provide a heat ray shielding film that can obtain a high heat ray reflectance and also maintain a stable heat ray reflectance and transparency even under a high humidity environment, and to provide a heat ray shielding medium having the heat ray shielding film.SOLUTION: A heat ray shielding film includes, on a base material, at least one unit where a low refractive index layer and a high refractive index layer are laminated, as a heat ray reflective layer, in which the high refractive index layer contains a metal oxide and a polymer having a triazine unit.
