Abstract
There is provided an aggregate of metal fine particles, a metal fine particle dispersion liquid, a heat ray shielding film, a heat ray shielding glass, a heat ray shielding fine particle dispersion body and a heat ray shielding laminated transparent base material, having sufficient properties as a solar radiation shielding material which widely shields a heat ray component included in sunlight, and in which selectivity of a light absorption wavelength is controlled, wherein when a shape each metal fine particle is approximated to an ellipsoid, and mutually orthogonal semi-axial lengths are defined as a, b, c (a≥b≥c) respectively, an average, a standard deviation, and a distribution, etc., of the values of the aspect ratio a/c of the metal fine particles are in a predetermined range, and the metal is silver or a silver alloy.
