Abstract
An adhesive composition layer that transmits light in a visible light region and absorbs light in a near-infrared region, has a low haze value, and a near-infrared absorbing film, a laminated structure, a laminated body using the above adhesive composition and adhesive layer, and an adhesive layer, a near-infrared absorbing film, a laminated structure, a laminated body, and an adhesive composition containing composite tungsten oxide fine particles, a dispersant, a metal coupling agent having an amino group, an adhesive, and a crosslinking agent, wherein the composite tungsten oxide fine particles include a hexagonal crystal structure, and the composite tungsten oxide fine particles have lattice constant values such as 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 the composite tungsten oxide fine particles having an average particle size of 100 nm or less.
