Abstract
To provided a near-infrared shielding film which is excellent in durability and film flexibility and has high visible light transmittance and an excellent near-infrared shielding property, a production method thereof, and a near-infrared shielding body being formed by being provided with the near-infrared shielding film. The near-infrared shielding film includes an optical interference film formed by alternately laminating a high refractive index layer containing a first water-soluble polymer and first metal oxide particles and a low refractive index layer containing a second water-soluble polymer and second metal oxide particles, on a substrate, in which the first metal oxide particles are particles formed by coating titanium oxide particles with silicon-containing hydrated oxide.
