PROBLEM TO BE SOLVED: To provide a light transmissive composition excellent in light transmittance.SOLUTION: A light transmissive composition of the present invention is a light transmissive composition in which nano hollow silica particles are dispersed on a light transmissive matrix, primary particles of the nano hollow silica particles have a three-dimensional shape, and the nano hollow silica particles are agglomerated on the matrix. It is preferable that air is contained in the agglomerated particles, a mean particle size of the primary particles is not more than 500 nm, a wall thickness is not more than 30 nm, a porosity is not less than 40%, and a mean particle size of the agglomerated particles is not more than 1500 nm.SELECTED DRAWING: Figure 3 【課題】光透過率に優れた光透過性組成物を提供する。【解決手段】本発明の光透過性組成物は、光透過性のマトリックスにナノ中空シリカ粒子を分散させてなる、光透過性組成物であって、ナノ中空シリカ粒子は、その１次粒子の形状は立方体状であり、かつマトリックスにおいて凝集している。凝集した粒子には空気が内包され、１次粒子の平均粒子径は５００ｎｍ以下であり、壁厚は３０ｎｍ以下であり、空隙率は４０％以上であり、凝集した粒子の平均粒子径は１５００ｎｍ以下であることが好ましい。【選択図】図３
