Beschreibung
Zusammenfassung:	A battery includes a positive electrode having a first strip shape and a positive electrode lead, and a negative electrode having a second strip shape and a negative electrode lead. First ends of the positive electrode and the negative electrode in a longitudinal direction are on an inner peripheral side, and second ends of the positive electrode and the negative electrode in the longitudinal direction are on an outer peripheral side. The positive electrode lead and the negative electrode lead are extended out from a first end side in a width direction of the positive electrode and the negative electrode, and a first thickness of the positive electrode on the first end side is thinner than a second thickness of the positive electrode on a second end side in the width direction.
