A method for manufacturing an electrode, the method comprising: 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, wherein the electrode active material is repeatedly applied so that the initial electrode includes coating portions (42a, 44a; 42b, 46b) having a length of 'a+b' and non-coating portions, wherein each of the coating portions (42a, 44a; 42b, 46b) is an area coated with the electrode active material and each of the non-coating portions is an area which is not coated with the electrode active material; and a first cutting step of cutting the initial electrode coated with the electrode active material to manufacture a plurality of middle-stage electrodes through a first cutting line that is a line for cutting the initial electrode, wherein the first cutting line is formed only on the coating portions (42a, 44a; 42b, 46b), wherein, at least one of the plurality of middle-stage electrodes include a coating portion having a length 'a', a non-coating portion and a coating portion having a length 'a', at least one of the plurality of middle-stage electrodes include a coating portion having a length 'b', a non-coating portion and a coating portion having a length 'b', wherein each of the middle-stage electrodes comprises a coating portion that is an area coated with the electrode active material and a non-coating portion that is an area which is not coated with the electrode active material, and the coating portions are spaced apart from each other by the non-coating portion, and wherein 'a' and 'b' have different values. 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, wherein the electrode active material is repeatedly applied so that the initial electrode includes coating portions (42a, 44a; 42b, 46b) having a length of 'a+b' and non-coating portions, wherein each of the coating portions (42a, 44a; 42b, 46b) is an area coated with the electrode active material and each of the non-coating portions is an area which is not coated with the electrode active material; and a first cutting step of cutting the initial electrode coated with the electrode active material to manufacture a plurality of middle-stage electrodes through a first cutting line that is a line for cutting the initial electrode, wherein the first cutting line is formed only on the coating portions (42a, 44a; 42b, 46b), wherein, at least one of the plurality of middle-stage electrodes include a coating portion having a length 'a', a non-coating portion and a coating portion having a length 'a', at least one of the plurality of middle-stage electrodes include a coating portion having a length 'b', a non-coating portion and a coating portion having a length 'b', wherein each of the middle-stage electrodes comprises a coating portion that is an area coated with the electrode active material and a non-coating portion that is an area which is not coated with the electrode active material, and the coating portions are spaced apart from each other by the non-coating portion, and wherein 'a' and 'b' have different values.
