Abstract
The present disclosure aims to provide a nonaqueous electrolyte secondary battery in which electrode plate deformation in association with charge/discharge cycles is suppressed. A nonaqueous electrolyte secondary battery which is one example of an embodiment of the present disclosure includes a winding type electrode body (). The electrode body () is provided with a tape () adhered to an exposed portion () which is provided at an outermost circumferential surface and at which a negative electrode collector is exposed. The tape () is adhered to the exposed portion () so as not to be overlapped with at least one of a winding-finish side end () of positive electrode mixture layers and a winding-finish side end () of negative electrode mixture layers in a radius direction of the electrode body ().
