Summary:PROBLEM TO BE SOLVED: To provide a method for manufacturing silver powder by which silver powder having a surface moisture content suitable for conductive pastes in which highly water-soluble organic solvents are used can be manufactured. SOLUTION: The method for manufacturing silver powder in which a reducing agent is added to an aqueous reaction system containing silver ions to precipitate silver particles by reduction is characterized in that: two or more dispersing agents, preferably, e.g. a hydrophobic dispersing agent, such as benzotriazole, stearic acid and oleic acid, and a hydrophilic dispersing agent, such as gelatin and collagen peptide, are added to a slurry-like reaction system before, after or in the course of the reduction precipitation of silver particles.
