Abstract

One embodiment of the present invention provides an electrolytic copper foil includes a copper layer and has a width direction weight deviation of 5% or less calculated according to Equation 1 below, a tensile strength of 25 kgf/mm2 to 62 kgf/mm2, and a valley depth-to-thickness (VDT) of 3.5 to 66.9 calculated according to Equation 2 below. [Equation 1] width direction weight deviation (%) = (standard deviation of weight/arithmetic mean of weight) 100, and [Equation 2] VDT = [thickness of electrolytic copper foil] / [maximum valley depth of roughness profile (Rv)].
