PROBLEM TO BE SOLVED: To easily connect an electrode to the terminal thereof without increasing the weight and manufacturing cost of a battery or capacitor, regardless of the position of an electrode terminal. SOLUTION: An electrode plate having the pre-formation part of an active material layer formed like a strip on the lateral end of a current collector is prepared, and an approximately hook type cutout is formed on the pre-formation part, thereby forming a plurality of approximately strip type lead parts in a lengthwise direction. Then, the pre-formation part is projected toward a take-up shaft, and each of the lead parts has a forward end sequentially arrayed in a preset direction and wound. In addition, the lead parts are respectively overlapped on each other partly and connected to an electrode terminal. This electrode current collecting structure is capable of forming a long lead without enlarging the projection breadth of the pre-formation part. |
