PROBLEM TO BE SOLVED: To provide an aqueous dispersion of metal nanoparticles, which has practically sufficient dispersibility, and to provide a production method of the dispersion.SOLUTION: The production method of the aqueous dispersion of metal nanoparticles includes: a step for mixing the metal nanoparticles (a) and amines (b) or a step for mixing the metal nanoparticles (a) and a &bgr;-1,3-1,6 glucan (c) having a branching degree of the &bgr;-1,6 bond to the &bgr;-1,3 bond of 50-100% in a solution which is adjusted to alkalinity by using amines (b) as alkali; and a step for neutralizing the resulting mixed solution by the addition of a neutralizer (d). |
