Abstract
An electrode 13 has an active material layer 12 formed on each of two whole main surfaces of a current collector 11. A part of an electrode lead 14 overlaps the electrode 13. One end face of the electrode 13 in the width direction of the electrode 13 is flush with one end face of the electrode lead 14. Joints 15 are formed at the one end of the electrode 13 in the width direction. The joints 15 join the electrode 13 and the electrode lead 14 so as to provide electrical continuity between the exposed part of the current collector 11 at the one end face of the electrode 13 in the width direction and the electrode lead 14. The joints 15 are formed, for example, by plasma welding.
