Summary:An electrolytic copper foil is disclosed. The electrolytic copper foil has an excellent elongation by adjusting an average cross-sectional grain size on at least one surface area of the electrolytic copper foil, with respect to a cross-section perpendicular to a longitudinal direction, and a ratio of the grain size. An electrode for a secondary battery and a secondary battery including the electrolytic copper foil are disclosed.
