Abstract

A positive electrode terminal is inserted into a current-collector through hole formed, in a positive electrode current collector and riveted in a spot-faced hole formed in the positive electrode current collector. A protrusion is formed on a bottom surface of the spot-faced hole so as to extend around the current-collector through hole, and a riveted portion of the positive electrode terminal covers the protrusion. The riveted portion of the positive electrode terminal is weld-connected to an edge of the spot-faced hole.
