PROBLEM TO BE SOLVED: To provide an electrode winding type battery facilitating current collecting processing work and having a small space for the current collecting processing. SOLUTION: This battery has an electrode body 50 constituted by spirally winding a strip positive electrode, a negative electrode, and a separator sandwiched between the positive electrode and the negative electrode. Here, at least one of the positive electrode and the negative electrode has plural strip-like current collecting leads 14, 24 extending from one end portion of a winding end surface 51 of the electrode body 50 toward the winding axis direction of the electrode body 50. The plural current collecting leads 14, 24 are aligned on lines A, B radially extending on the winding end surface 51 of the electrode body 50, and they are connected integrally. |
