PROBLEM TO BE SOLVED: To provide a battery for preventing an electrode element 1 from becoming a high temperature, preventing a separator from being torn, and preventing the electrode element 1 from thermally running away. SOLUTION: In this battery having the electrode element 1 including a sheet- like electrode and the separator, and a lead 3 arranged along a side surface of the electrode element 1, connecting a lower end part of the lead 3 to a lower end part of the electrode element 1, and positioning an upper end part of the lead 3 above an upper end part of the electrode element 1, a heat insulating material 8 is arranged between a side surface upper end part of the electrode element 1 and the lead 3. |
