Beschreibung
Zusammenfassung:	A secondary battery includes a rectangular exterior body having an opening and containing a first electrode assembly and a second electrode assembly, a sealing plate sealing the opening, and a positive-electrode current collector. The sealing plate has an electrolytic solution introduction hole. The first electrode assembly includes a first insulating sheet on an outermost surface thereof adjacent to the second electrode assembly. The second electrode assembly includes a second insulating sheet on an outermost surface thereof adjacent to the first electrode assembly. A first tape is attached to both an outermost surface of a first positive-electrode tab group and the first insulating sheet. A second tape is attached to both an outermost surface of a second positive-electrode tab group and the second insulating sheet. At least one of the first tape and the second tape is located to face the electrolytic solution introduction hole.
