形リチウム電池。[Claims for Utility Model Registration] An electrode group consisting of a strip-shaped positive electrode and a negative electrode stacked on top of each other with a separator interposed therebetween and spirally wound is housed in a battery case, and an insulating electrode is placed above the electrode group. In the cylindrical spiral type lithium battery, a ring-shaped group presser plate is mounted, and the group presser plate is locked by an annular protrusion formed by beading the battery can opening inward on the upper side of the group presser plate. A cylindrical spiral type lithium battery, characterized in that at least one notch is formed on the outer periphery of the group pressing plate, and the inner edge of the notch is located inside the inner edge of the annular protrusion.
