PROBLEM TO BE SOLVED: To provide a method for manufacturing silver coated conductive powder which is capable of forming a uniform silver plating layer having a high adhesion property on a nickel alloy plating layer formed on the surface of a powdery core material even if a cyano compound is not used. SOLUTION: In this method for manufacturing the silver coated conductive powder by treating the surface of the core material consisting of an organic material or inorganic material with an electroless nickel-phosphorus plating liquid, then treating the surface with an electroless silver plating liquid containing a water-soluble silver salt and a complexing agent, an organic compound containing sulfurous acid or a sulfite or imide group or amide group is used as the complexing agent for the electroless silver plating liquid.
