To provide a method for improving light transmittance without reducing the concentration of inorganic particles in a dispersion of the inorganic particles produced by using a bead mill.
The method for producing the dispersion of the inorganic particles, containing the inorganic particles having 1 and 50 nm average particle diameter and 4.5 specific gravity, a dispersing agent and an organic solvent includes a step for carrying out the dispersion treatment by the bead mill using zirconia beads, a step for carrying out a centrifugal separation treatment under a condition in which the A-value of the following equation (1) is 200 and 1,100: A=(K-factor)[viscosity (mPa s) of dispersion][treating time (min)] (1), and a step for collecting the liquid component in order.
