In a method for producing dense sheet-form electrolytic copper by electrowinning, the electrolyte contains a polyethylene glycol additive as a smoothening agent. In the prior art method, stirring is necessary. In an electrowinning method without stirring, the current concentrates on the edge portion of cathode 2 . This current concentration is mitigated by means of conducting the electrolyzing current through a window 6 b of a shielding plate 6 located in the vicinity of a cathode 2.
