PROBLEM TO BE SOLVED: To provide a battery unit capable of stably holding a connection section of a battery pack formed by laminating plural flat storage batteries 1a, 1b, 1c, and 1d.SOLUTION: Plural flat storage batteries are laminated in its thickness direction, and serially connected to each other, so as to form a battery pack 1. Positive electrodes 1a1, 1b1, 1c1, and 1d1, and negative electrodes 1a2, 1b2, 1c2, and 1d2 of the flat storage batteries adjacent to each other in a lamination direction are connected to conductive sections 6a1, 6b1, 6c1, 6d1, 6a2, 6b2, 6c2, and 6d2. The flat storage batteries and the conductive sections 6a1-6d2 are held by support members 71-74. The flat storage batteries and the support members are alternately laminated in the thickness direction. Thereby, even when rigidity of the positive electrodes and the negative electrodes is small, each electrode is connected to the conductive section with large rigidity, and therefore, it is finally and stably held by the support members. |
