A nonaqueous electrolytic secondary battery according to the present invention includes: a positive electrode having a positive-electrode current collector and a positive-electrode active-material layer; a negative electrode having a negative-electrode current collector and a negative-electrode active-material layer; a separator interposed between the positive electrode and the negative electrode; a nonaqueous electrolyte; a positive-electrode lead; and an insulating tape covering a portion of the positive electrode. Furthermore, the positive-electrode current collector has an exposed section not carrying the positive-electrode active-material layer thereon, the positive-electrode lead is connected to the exposed section, and the positive-electrode lead has: an extended section projected from the exposed section; and an overlapping section overlapping the exposed section. Furthermore, at least a portion of the exposed section, together with at least a portion of the overlapping section, is covered with the insulating tape. The insulating tape has a substrate material layer and an adhesive layer, and the adhesive layer includes an adhesive agent and an insulating inorganic material. |
