PROBLEM TO BE SOLVED: To obtain an electrolytic copper powder which has more improved formability and can be formed to a higher strength than conventional electrolytic copper powder without developing the dendrites of the electrolytic copper powder more than required. SOLUTION: There is provided a method of producing an electrolytic copper powder for precipitating the electrolytic copper powder by making electric current to flow to an electrolyte, with the object of scaling down the size of crystallites composing the electrolytic copper powder in order to precipitate the electrolytic copper powder which can be formed to a high strength by increasing the strength of the electrolytic copper powder itself. In the method, the electrolyte is obtained by adding one or more kinds selected from among tungstates, molybdates and sulfur-containing organic compounds into an aqueous solution of copper sulfate.
