An electrode mixture paste application method includes: a first step of unwinding a core material () wound in a coil shape; a second step of applying an electrode mixture paste () to both sides of the core material; a third step of adjusting an application amount of the electrode mixture paste; a fourth step of drying a paste-coated sheet with the electrode mixture paste applied to the both sides thereof; and a fifth step of winding the paste-coated sheet () in a coil shape, wherein, in the fifth step, the paste-coated sheet is wound such that each of widthwise edge portions of a mixture-formed portion () is prevented from sequentially overlapping itself. This can achieve a stable method for applying an electrode mixture paste in which the deformation of an electrode caused by a dog-bone shape generated at both edge portions of a mixture-formed portion can be avoided.
