摘要： The current-collecting lead for being welded to a collector welded to an upper portion of an electrode group and also to a sealing assembly of an cylindrical secondary battery includes: a flat surface part welded to the collector, and a top part formed to be curved and protrude approximately in the shape of a dome from the flat surface part and welded to the sealing assembly. A central opening is formed at a central portion of the top part. Around the central opening, a plurality of welding projections are formed to protrude toward the sealing assembly. The welding projections serve as welding spots to the sealing assembly. The top part is deformed by a pressing force from the sealing assembly to be brought into surface contact with a corner portion of a convex portion formed on a lower surface of the sealing assembly.
