PROBLEM TO BE SOLVED: To provide a continuous surface treatment method for copper foil and an apparatus therefor realizing uniform treatment without narrowly setting the width of an anode plate nor causing the lowering of the treating capacity in both sides (vicinities of the edges) in the width direction of copper foil and excessive electrodeposition to the edge parts, and realizing improvement in the productivity. SOLUTION: Copper foil is continuously passed to the fronts of anode plates set in an electrolytic cell and opposite to each other, and surface treatment is performed. In this case, a pair of straightening plates are arranged in the space between both edge parts of the copper alloy to be passed and both edge parts of the anode plates, and then, the surface treatment is performed.
