PROBLEM TO BE SOLVED: To provide electrolytic copper foil which allows the implementation of continuous operation under high-current density, has a good adhesion property to a cathode and is good in mechanical characteristic (more particularly tensile strength and folding endurance at ordinary temperature) and a method for manufacturing the same. SOLUTION: The electrolytic copper foil having mechanical characteristics of >=500 N/mm2 in tensile strength and >=150 times in folding endurance formed by adding chlorine ions, gelatin, active sulfur-containing component and oxyethylene surfactant into an acidic copper electrolytic bath and subjecting the copper foil to an electrolytic treatment and the method for manufacturing the same.
