PROBLEM TO BE SOLVED: To provide a method for manufacturing electrolytic copper foil which is capable of remarkably improving the yield of the electrolytic copper foil, shortening the time required for changing the width of the electrolytic copper foil, lessening working labor and reducing the cost of equipment. SOLUTION: Voltage is impressed between an anodic electrode body 3 and a cathodic drum 4 in the state of applying and sticking a non-conductive material B at a prescribed width to an outer peripheral surface 4a of the cathodic drum 4 and while the cathodic drum 4 is kept rotated, copper is deposited and adhered to the outer peripheral surface 4a of the cathodic drum 4, by which the electrolytic copper foil C of the prescribed width is formed. After the electrolytic copper foil is formed, high-pressure steam is blown to the outer peripheral surface 4a of the cathodic drum 4 to dissolve and remove the non-conductive material B from the outer peripheral surface 4a.
