The present invention relates to an electrode manufacturing apparatus and method, which can improve the productivity of an electrode in comparison with a conventional technology. In order to achieve the objective, an aspect of the present invention provides an electrode manufacturing method comprising: a step of preparing a current collector; an application step of applying an electrode active material to one surface or both surfaces of the current collector to manufacture an initial electrode; and a first cutting step of cutting the initial electrode coated with the electrode active materialto manufacture a plurality of intermediate electrodes, wherein the first cutting step is carried out by cutting the initial electrode in such a manner that at least a part of the plurality of intermediate electrodes is different in length from the remaining plurality of intermediate electrodes.
