Abstract
A method for producing a fine particle dispersion includes the steps of reducing a metal ion to form a fine particle dispersion aqueous solution; adding an aggregation accelerator into the fine particle dispersion aqueous solution so that agglomerated or precipitated fine particles are separated to obtain fine particles; and re-dispersing the fine particles into an organic solvent containing an organic solvent having an amide group, a low boiling point organic solvent having a boiling point between 20° C. and 100° C. at a normal pressure, and an organic solvent having a boiling point higher than 100° C. at a normal pressure and containing an alcohol and/or a polyhydric alcohol.
