Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a metal fine particle composition, capable of effectively dispersing metal fine particles.SOLUTION: The method for producing a metal fine particle composition comprises the steps of: A) preparing a slurry containing metal fine particles coated with a primary amine and an organic solvent; B) adding a nonaqueous polymer dispersant having a secondary or tertiary amino group to the slurry to substitute at least part of the primary amine with the nonaqueous polymer dispersant on the surface of the metal fine particles, thereby coating the metal fine particles with the nonaqueous polymer dispersant; and C) mixing the metal fine particles coated with the nonaqueous polymer dispersant with a solvent having a boiling point within a range of 190-280°C in the presence of a viscosity modifier, to set the viscosity at 23°C of a metal fine particle composition to 30 mPa s or less.
