PROBLEM TO BE SOLVED: To provide a dispersion of fine particles of a near-infrared shield material having an improved heat resistance and near-infrared shield fine particles containing the dispersion. SOLUTION: The near-infrared shield fine particles included in the dispersion of fine particles of the near-infrared shield material is a mixture of a composite tungsten oxide having a hexagonal crystal structure expressed by the formula MyWOz (wherein, M is not less than one kind of element selected from among Cs, Rb, K, Na, Ba, Ca, Sr, and Mg; W is tungsten; O is oxygen; 0.1≤y≤0.5, 2.2≤z≤3.0), and zinc oxide fine particles.
