Abstract
A near-infrared shielding material fine particle dispersion body, a near-infrared shielding body, and a near-infrared shielding laminated structure containing composite tungsten oxide that exhibits more excellent near-infrared shielding function than that of a conventional near-infrared shielding material fine particle dispersion body, near-infrared shielding body, and near-infrared shielding laminated structure, and a method for producing the same. Also, a near-infrared shielding material fine particle dispersion body in which near-infrared shielding material fine particles are dispersed in a solid medium. The near-infrared shielding material fine particles are composite tungsten oxide fine particles containing a hexagonal crystal structure, in which a lattice constant of the composite tungsten oxide fine particles is 7.3850 Å or more and 7.4186 Å or less on the a-axis, and 7.5600 Å or more and 7.6240 Å or less on the c-axis, and a particle size of the near-infrared shielding material fine particles is 100 nm or less.
