In the present method of producing a colloidal solution of metal nano-particles in which a pair of metal electrodes is oppositely arranged in an aqueous electrolytic solution in which metal salts are dissolved and a current is applied to the two electrodes while stirring the aqueous electrolytic solution using stirring means so that metal ions in the solution are reduced to extract metal nano-particles, the method is characterized by adding polysorvate to the aqueous electrolytic solution to coat the surface of metal nano-particles extracted in the solution, thereby preventing agglomeration of the metal nano-particles. |
