METHOD FOR MANUFACTURING ELECTRODE AND METHOD FOR MANUFACTURING BATTERY

According to one embodiment, a method for producing an electrode, includes a step for applying tensile force. The electrode includes a strip current collector, a current collector exposed portion which is formed on at least one long side of the strip current collector and in which no active material-containing layer exists on each surface thereof, and an active material-containing layer formed on at least a part of the strip current collector excluding the current collector exposed portion. In the step for applying tensile force, arranging a strip electrode plate on a roller including a step portion projected from a circumferential surface and a recessed portion adjacent to the step portion such that the current collector exposed portion is positioned on the step portion and the active material-containing layer is positioned on the recessed portion, and then applying tensile force to the strip electrode plate in a longitudinal direction of the strip electrode plate.
