【Task】 Infrared shielding material fine particles in which tungsten oxide fine particles and / or composite tungsten oxide fine particles are dispersed in a medium that is transparent in the visible light region, absorbs in the near infrared region, and suppresses color change due to ultraviolet rays. Provide a dispersion. [Solution] An infrared shielding material fine particle dispersion liquid in which tungsten oxide fine particles represented by Cs 0.33 WO 3 and 0.01% or more and 20% or less of a hindered amine light stabilizer are dispersed in a medium.
