PROBLEM TO BE SOLVED: To provide a dispersion composition in which metal oxide fine particles can be successfully dispersed and which provides a cured article after being cured, the cured article achieving both of good optical performance and good surface smoothness.SOLUTION: The dispersion composition related to the present invention contains (A) a dispersible particle which is metal oxide fine particle having an average diameter of less than 50 nm, (B) a dispersant consisting of a compound represented by the formula (1) and (C) a polymerizable compound. The (B) dispersant is blended in the range of 3 to 20 mass% based on total solid component. (1), where R: a linear alkyl group or a linear alkenyl group having 3 to 24 carbon atoms, AO: an oxyalkylene group having 1 to 4 carbon atoms, n:average addition molar number of alkylene oxide, 5 to 30, X: a connecting group consisting of a carbon atom, a hydrogen atom and/or an oxygen atom.SELECTED DRAWING: None 【課題】 金属酸化物微粒子を良好に分散できるとともに、硬化後の硬化物において良好な光学性能と良好な表面平滑性との双方を実現する分散体組成物を提供する。【解決手段】 本発明に係る分散体組成物は、平均粒径が５０ｎｍ未満の金属酸化物微粒子である（Ａ）分散質粒子と、下記式（１）で示される化合物からなる（Ｂ）分散剤と、（Ｃ）重合性化合物とを含有している。（Ｂ）分散剤は、全固形分に対して３〜２０質量％の範囲内で配合される。【化４】（式（１）のＲ：炭素数３〜２４の直鎖アルキル基もしくは直鎖アルケニル基、ＡＯ：炭素数１〜４のオキシアルキレン基、ｎ：アルキレンオキシドの平均付加モル数５〜３０、Ｘ：炭素原子、水素原子および／または酸素原子からなる連結基。）【選択図】 なし
