PROBLEM TO BE SOLVED: To provide a battery pack in which plural single batteries can be positioned without any dedicated jig for positioning tabs by interlocking the tabs of the single batteries adjacent in a lamination direction.SOLUTION: Plural flat single batteries 1 in which tabs 2 are led out in parallel to flat surfaces 4 are laminated to provide a battery pack 5. Each tab 2 has a base portion 2a, and a bent piece 2b which is bent from the tip of the base portion 2a. The base portion 2a has a slender opening portion 6 extending in a tab width direction Y along a ridge line 7 as a start position of the bending, and the bent piece 2b has a tongue piece portion 2q having a width corresponding to the slender opening portion 6. The tongue piece portion 2q of the tab 2 of one single battery 1 is inserted in the opening portion 6 of the tab 2 of the single battery 1 adjacent in the lamination direction Z.SELECTED DRAWING: Figure 3 |
