  "textContent": "A cylindrical battery provided with: an electrode body in which a positive electrode plate and a negative electrode plate are rolled with a separator being disposed therebetween; an electrolytic solution; an external packaging can which has a bottomed cylindrical shape and which houses the electrode body and the electrolytic solution; and a sealing plate which is fixed by swaging to an opening of the external packaging can with a gasket therebetween. As viewed in a planar view, the sealing plate is formed to have a circular shape, and has a central part recessed inward of the battery. In the sealing plate, an outer circumferential edge fixed by swaging to the external packaging can is configured to bifurcate into a first portion and a second portion in the thickness direction.",
