PROBLEM TO BE SOLVED: To provide a ply structure for shielding heat ray which uses composite tungsten oxide fine particles with excellent heat ray shielding properties, and exerts excellent optical characteristics and excellent weather resistance.SOLUTION: There is provided a ply structure for shielding heat ray which is formed by interposing a middle layer containing fine particles having a heat ray shielding function and hydroxide of metal between two ply plates selected from plate glass, plastic, and plastic containing fine particles having a heat ray shielding function and hydroxide of metal. The fine particles having the heat ray shielding function are composite tungsten oxide fine particles, and the hydroxide of metal is contained by 1 pt.wt. or more and 100 pts.wt. or less to 100 pts.wt. of the composite tungsten oxide fine particle. |
