PROBLEM TO BE SOLVED: To provide a fine heat ray-shielding particle dispersed body and a heat ray-shielding laminated transparent substrate, having characteristics sufficient as a solar radiation shielding material with which selectivity of light absorption wavelength is controlled, and which widely shields heat ray components included in sunlight.SOLUTION: A fine heat ray-shielding particle dispersed body is provided which is included at least fine heat ray-shielding particles and a thermoplastic resin, in which: the fine heat ray-shielding particles are assembly of fine metal particles respectively having a disk shape and/or a rod shape; and when the shape of the fine metal particle is approximated by an ellipsoid, and respective mutually orthogonal half axis lengths of the fine metal particle are represented by a, b, and c (provided that a≥b≥c), average value, standard deviation, distribution, etc., of the aspect ratio a/c of the fine metal particle are in a predetermined range, and the metal is silver or a silver alloy. A heat ray-shielding laminated transparent substrate using the fine heat ray-shielding particle dispersed body is also provided.SELECTED DRAWING: None |
