Abstract: A secondary battery includes: an electrode body including an electrode main body, a collector foil protrusion section, and a collector foil connection portion; a first collector terminal including a first extension part that is welded to the collector foil connection portion; and a second collector terminal that is a member separate from the first collector terminal and includes a second extension part welded to the collector foil connection portion. The first extension part and the second extension part are located on the opposite sides of the collector foil connection portion. The secondary battery includes a welded joint at which both the first extension part and the second extension part are welded to the collector foil connection portion such that the first extension part, the second extension part, and the collector foil connection portion are united. The first collector terminal and the second collector terminal are united through the welded joint.
