  "textContent": "A cylindrical battery having a bottomed tubular exterior can; an electrode body in the exterior can and around which a long positive electrode and a long negative electrode are wound with a separator therebetween; a plurality of negative-electrode lead parts extending from a long negative-electrode current collector of the negative electrode toward the bottom part of the exterior can; a first current-collector plate that is disposed on the bottom part side of the electrode body and that has at least two through-holes at the positions different from each other in the radial direction; and a second current-collector plate disposed between the first current-collector plate and the bottom part. The negative-electrode lead parts each pass through any one of the through-holes. Leading-end portions of the plurality of negative-electrode lead parts are sandwiched between the first current-collector plate and the second current-collector plate, and are electrically connected to the second current-collector plate.",
