Abstract
The present disclosure provides a non-aqueous electrolyte secondary battery having a stable open-circuit voltage. An electrode for a non-aqueous electrolyte secondary battery according to one embodiment includes a belt-like current collector, a mixture layer formed on each surface of the current collector, and a lead bonded to an exposed portion of the current collector where the surfaces of the current collector are exposed, the lead extending from one end of the current collector, the one end and another end constituting both ends of the current collector in the width direction. In an electrode for a non-aqueous electrolyte secondary battery according to one embodiment, a mixture layer is formed on at least one surface of a current collector in the width direction of the current collector and adjacent to an exposed portion on one end side.
