PROBLEM TO BE SOLVED: To disperse fine particles of any particle size in order to further reduce the hygroscopicity of a resin molded body as much as possible on the premise of imparting flame retardancy to a resin to which inorganic fine particles are added. Therefore, it is possible to provide a molded / cured product that is excellent in flame resistance, moisture absorption resistance, mechanical properties, heat resistance, etc. while being halogen-free and phosphorus-free. A dispersion in which inorganic fine particles, which are hydrolyzed condensates of alkoxide and / or metal carboxylate, are dispersed in a dispersion medium, wherein the inertial radius of the inorganic fine particles is 50 nm or less, and inertia A dispersion of inorganic fine particles, wherein the mass ratio of fine particles having a radius of less than 10 nm and fine particles having an inertial radius of 10 nm to 50 nm is 1:99 to 40:60. |
