Summary:A method for manufacturing an electrode plate including a current collector and an active material layer includes preparing, forming, and pressing. In the preparing, a mixture is prepared by kneading an active material. In the forming, the active material layer is formed on the current collector by applying the mixture to the current collector. In the pressing, the active material layer is pressed so that active material layer has a predetermined thickness. The mixture applied to the current collector has a weight per unit area based on a specific surface area of the active material used in the mixture and a tapped density of the active material used in the mixture.
