  "textContent": "A secondary battery includes an electrode body, a battery case, and an electrode terminal. The electrode body has a foil collecting portion. The electrode terminal corresponding to at least one of a positive electrode and a negative electrode is electrically connected to the foil collecting portion via a current collector terminal. The current collector terminal is joined to the foil collecting portion. The foil collecting portion has a joining mark composed of a plurality of recesses on a surface on an opposite side of the foil collecting portion from a surface joined to the current collector terminal. The joining mark has two corners on an inner side of the electrode body and two corners on an outer side of the electrode body, and only the two corners on the inner side of the electrode body have a chamfered shape.",
