PROBLEM TO BE SOLVED: To provide a battery capable of preventing immersion of lead part into an electrode bundle even when the lead part is deformed due to an external shock.SOLUTION: The battery includes lead parts 32 and 42 which are disposed being faced to an outer plane of either a positive electrode surface 20a or a negative electrode surface 20b of an electrode bundle 20, and which are connected to the outer plane of either a positive electrode plate 21 or a negative electrode plate 22. The battery also includes blade parts 33 and 43 each of which is integrally extended being folded from the front end of the lead parts 32, 42 in a thickness direction of the electrode bundle 20 so as to cover a part of the positive electrode surface 20a or the negative electrode surface 20b while ensuring an insertion part 100 where the positive electrode surface 20a or the negative electrode surface 20b is exposed. |
