A slitter according to an embodiment of the present invention for solving the above problem includes: an upper knife disposed above the electrode plate to rotate, thereby cutting the electrode plate; and a lower knife disposed below the electrode plate to partially overlap the upper knife and rotate, thereby cutting the electrode plate together with the upper knife, wherein the upper knife includes: a first inner surface extending to be inclined from a tip formed at the lowermost end to the lower knife; and an outer circumferential surface extending to be inclined from the tip to an opposite side of the lower knife, wherein the first inner surface has an inclination at a first angle from a vertical line V that is perpendicular to a rotation axis that serves as a rotation center of the upper knife, and the outer circumferential surface has an inclination at a second angle from the vertical line.
