An object of the present invention is to provide heat ray shielding particles having excellent weather resistance. A heat ray shielding particle, which is a particle containing a composite tungsten oxide, The composite tungsten oxide contains M element (M: one or more elements selected from H, He, alkali metal, alkaline earth metal, rare earth element, etc.), tungsten and oxygen, M element seat occupancy (S) is 85% or more, The composite tungsten oxide has one or more crystal structures selected from tetragonal, cubic, hexagonal, and monoclinic; The lattice strain of the composite tungsten oxide determined by the X-ray diffraction method is 0.25% or less, Provided is a heat ray shielding particle having an average particle diameter of 5 nm to 200 nm.
