Zusammenfassung:	A nonaqueous electrolyte secondary battery according to one embodiment of the present invention includes a pressure-sensitive current interrupt mechanism. An insulating tape is bonded onto a positive electrode mixture layer in at least one of a winding start-side edge portion and a winding end-side edge portion of a positive electrode plate in a flat wound electrode body at a position opposing to a separator, the insulating tape extending in a widthwise direction of the positive electrode mixture layer.
