Abstract: A battery includes a negative electrode body wound to be flat. The negative electrode body has a plurality of negative electrode main bodies arranged in a line in a negative electrode connection direction in a developed state, and at least one negative electrode connection portion connecting a pair of negative electrode main bodies adjacent in the developed state among the plurality of negative electrode main bodies. The at least one negative electrode connection portion is folded back such that the plurality of negative electrode main bodies overlap each other. A dimension of each of the plurality of negative electrode main bodies in the negative electrode connection direction decreases with separation from an outer end side negative electrode main body. A dimension of the at least one negative electrode connection portions in the negative electrode connection direction increases with separation from an inner end side negative electrode connection portion.
