Provides a method for producing a fine particle dispersion, such as dispersibility and storage stability are excellent metal. A method for producing the fine particles of metal such as the average primary particle diameter 1~150nm fine particle dispersion which is dispersed in an organic solvent, by reducing the metal ions by metal ions reduced in the liquid phase with an aqueous solution with a polymer dispersant is dissolved the process of the fine particles of average primary particle diameter is 1~150nm form a fine particle dispersion aqueous solution which is dispersed so covered with a polymer dispersant (step 1), fine particles dispersed in said aqueous solution, and stirred by adding a coagulation promoting agent, the fine particles an organic group having coagulation or precipitation then, to remove the aggregated or precipitated fine particles from the aqueous solution, a metal, an alloy, and a step for obtaining the fine particles made of one or more kinds of metal compounds (process 2), an the particulate amide solvent (a) 25~70% by volume, the boiling point of the low boiling point of the organic solvent having a boiling point of 20~100 ℃ in the normal pressure (B) 5~25% by volume, and the atmospheric pressure exceeds 100 ℃, also 1 molecule or 2 or more hydroxyl leather having alcohol and / or polyhydric comprising the organic solvent (C) a step of re-dispersed in an organic solvent containing 5 to 70% by volume (step 3) comprising the alcohol, the production of fine particle dispersion Way.
