Abstract: Provided are a cured material having a high refractive index for an optical member obtained by preparing a stable dispersion with a small amount of dispersant, and a process for producing dispersion of fine inorganic particles which is capable of drastically shortening the dispersion process time without causing overdispersion under the conditions of high solid concentration and without using media having a small particle size, which are very expensive and for which available dispersing machines are limited. Provided are a process for producing dispersion of fine inorganic particles using a media type wet dispersing machine, which includes supplying the following (A) to (D) to the wet dispersing machine, provided that (D) is supplied last to the wet dispersing machine: (A) Zirconium oxide nanoparticle, (B) Silane coupling agent, (C) Dispersion medium, and (D) Dispersant; a curable composition containing a dispersion obtained by the producing process; and a cured material obtained therefrom.
