Abstract
Wound positive-electrode core body exposed pails are bundled and connected to a positive-electrode collector body. A tape is affixed straddling a separator positioned on the outermost surface of a winding electrode body, and the outermost surface of the wound positive-electrode core body exposed parts. The tape has a porous base material and an adhesive layer provided on the base material. The tape has a region in which the adhesive layer b is not provided on the base material a between the connection part between the tape and the separator positioned on the outermost surface of the winding electrode body, and the connection part between the tape and the outermost surface of the wound positive-electrode core body exposed parts.
