PROBLEM TO BE SOLVED: To provide a production method of an inorganic fine-particle dispersion solution which suitably disperses a primary inorganic fine particle having the average particle diameter of 30 nm or below, in the degree that light scattering-permeability ability as an optical component is satisfied, and also gives the viscosity suitable for handling to the dispersion solution. SOLUTION: In the production method of the inorganic fine-particle dispersion solution consists of dispersing a primary inorganic fine-particle having the average particle diameter of 30 nm or below in a solution, this method has a dispersion treatment step where a media having the average particle diameter of≥15μm and≤30μm is introduced into a mixed solution, in the state that the primary inorganic fine-particle having the average particle diameter of 30 nm or below is coagulated in a solvent, to be stirred to disperse the inorganic fine particle, and an ultrasonic wave is applied to the mixed solution in or just after this dispersion treatment.
