PROBLEM TO BE SOLVED: To provide a method for producing silver hyperfine particles by which a recovery rate is high, and the dispersion stability of silver hyperfine particles with the lapse of time is excellent, to provide a silver hyperfine particle-containing composition having excellent dispersion stability and adhesion with a base material, and to provide a conductive member having excellent adhesion with the base material and electric conductivity. SOLUTION: In the method for producing silver hyperfine particles where, into an aqueous medium mainly containing water, at least a water-soluble silver salt, a basic compound, a water-soluble polymer compound and a reducing agent are incorporated, and silver ions derived from the water-soluble silver salt are reduced so as to produce silver hyperfine particles, the basic compound is composed of a basic potassium salt. Further, the silver hyperfine particle-containing composition contains the silver hyperfine particles obtained thereby, and the conductive member is obtained thereby. COPYRIGHT: (C)2011,JPO&INPIT |
