NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

The purpose of the present disclosure is to prevent, in a nonaqueous electrolyte secondary battery, a tape adhered to an outermost peripheral surface of an electrode group from breaking due to charging and discharging. A nonaqueous electrolyte secondary battery according to one embodiment of the present disclosure includes a winding-type electrode group and tapes adhered to an outermost peripheral surface of the electrode group so that an electrode group winding end E is fixed to the outermost peripheral surface of the electrode group. The tapes include: two adhesive regions including a substrate layer and an adhesive layer; and a non-adhesive region sandwiched between the two adhesive regions and consisting only of the substrate layer. The non-adhesive region is disposed so as to extend across the winding end E, which is positioned on the outermost periphery of the electrode group, in the winding direction.
