Abstract: The present invention relates an apparatus and method for manufacturing an electrode, and more particularly, to an apparatus and method for manufacturing an electrode, which is capable of improving productivity of the electrode in comparison with the related art. According to an aspect of the present invention so at to achieve the above object, a method for manufacturing an electrode includes: a step of preparing a collector; a coating step of applying an electrode active material to one surface or both surfaces of the collector to manufacture an initial electrode; and a first cutting step of cutting the initial electrode coated with the electrode active material to manufacture a plurality of middle-stage electrodes, wherein, in the first cutting step, the initial electrode is cut so that at least one of the plurality of middle-stage electrodes has a length different from those of the other middle-stage electrodes.
