PROBLEM TO BE SOLVED: To provide electrically conductive composite powder which is usable as an electrically conductive filler material for electrically conductive paste, and is inexpensively and easily producible by reducing the amount of use of silver, and to provide a method for producing the same. SOLUTION: The molten metal of an Ag-Cu-X alloy composed of Ag, Cu and X (wherein, X is Ni, Fe or Co) and having a composition in two phase regions of liquid phases in the ternary system is atomized to be rapidly cooled, thereby electrically conductive composite powder is produced which has at least either structure where a fine dispersed phase of a Cu-X based alloy is dispersed into an Ag matrix or structure where a core part composed of a Cu-X-rich phase is surrounded by an Ag-rich phase.
