PROBLEM TO BE SOLVED: To provide a method for manufacturing a copper powder which has a uniform particle size, is superior in monodispersibility, and is suitable particularly for manufacturing a conductive paste. SOLUTION: This manufacturing method comprises suspending basic copper carbonate in a liquid containing a polyol, such as ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, polyethylene glycol, or glycerine, and then heating the liquid at an arbitrary temperature between 150°C and 350°C. Since the basic copper carbonate is easily decomposed by heat in the liquid containing the polyol and then immediately reduced by the polyol, the resultant metal copper powder has a small particle size, a uniform shape, and a superior monodispersibility.
