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. <EOS>
