ABSTRACT:
A method of manufacturing an electrode includes a preparatory step of preparing an electrode matrix comprising a collector and an active material containing layer formed on at least one face of the collector, at least one edge part of the collector including an exposed surface free of the active material containing layer, an edge part of the active material containing layer on a side close to the exposed surface including a thinner part having a thickness smaller than a maximum thickness of the active material containing layer; and a roll-pressing step of pressing the electrode matrix with a roll press.
