Abstract: A nonaqueous electrolyte secondary battery includes a roll-type electrode group including positive and negative electrode plates and a tape attached to the outermost circumferential surface of the electrode group. The tape has two adhesion regions including an adhesive layer and a non-adhesion region that is interposed between the two adhesion regions and is composed of a base material layer only. The non-adhesion region straddles the rolling-end edge of at least one of the positive or negative electrode active material layer on the roll inner side of the positive or negative electrode collector and the positive or negative electrode active material layer on the roll outer side of the positive or negative electrode collector in the positive or negative electrode plate when the electrode group is viewed from a roll center axis toward the outside of the roll.
