Abstract
In a rolling step of feeding an electrode hoop () having electrode mixture layers () formed on both sides of a band-shaped core () made of a metal thin plate to between a pair of mill rolls () for rolling, the electrode hoop () is fed so that side a is wound about one of the mill rolls if the electrode mixture layers () of the electrode hoop () have different average thicknesses, where the side a is one of the electrode mixture layers of the electrode hoop () having the smaller average thickness and side b is the other. This realizes a method for rolling an electrode hoop capable of making a rolled flat electrode even if the electrode mixture layers on both sides of the core have respective different thicknesses.
