PROBLEM TO BE SOLVED: To improve a bonding strength and a liquid leakage resistance at a leading-out position of each lead of a positive electrode and a negative electrode in a nonaqueous electrolytic battery housing a power generating element in an exterior case formed of a laminated sheet. SOLUTION: A positive electrode lead 3 is connected to a positive electrode plate of a group of laminating electrodes 2 housed in an exterior case 1 formed of a laminate sheet and a negative electrode lead 4 is connected to a negative electrode plate thereof. The positive electrode lead 3 and the negative electrode lead 4 are led out through a sealing edge P3 of the exterior case 1. A notch 15 is formed in a position where the positive electrode lead 3 and the negative electrode lead 4 pass the sealing edge P3. A PP sheet 25 is attached from both sides containing the notch 15. Consequently, a sealing property at a leading-out edge of the lead is strengthened and a liquid leakage is suppressed. |
