PROBLEM TO BE SOLVED: To provide a secondary battery excellent in the output characteristics.SOLUTION: Thickness of the terminal connection 6a of a positive electrode collector 6 is larger than that of the terminal connection of a negative electrode collector. The terminal connection 6a of a positive electrode collector 6 has a through hole 6g, and a positive electrode terminal 7 is inserted into the through hole 6g and caulked onto the terminal connection 6a. The terminal connection of a negative electrode collector has a through hole, and the negative terminal is inserted into the through hole and caulked onto the terminal connection. On the lower surface of the positive electrode terminal connection 6a, a recess 6f is formed around the through hole 6g, and the lower end 7x of positive electrode terminal 7 is arranged in a recess 6f.SELECTED DRAWING: Figure 5 |
