Provided is an assembled battery, which has a plurality of cells and a connecting member. Each of the cells has a negative electrode terminal and a positive electrode terminal. The connecting member has a plurality of thin portions, and the thick portions, i.e., the rest of the connecting member other than the thin portions. The thin portions are respectively welded to the positive electrode terminals or to the negative electrode terminals. In the case where the connecting member is connected to each of the positive electrode terminals of the cells, the area of each of the thin portions is equivalent to or more than the area of the connecting surface of each of the positive electrode terminals. In the case where the connecting member is connected to each of the negative electrode terminals, the area of each of the thin portions is equivalent to or more than the area of the connecting surface of each of the negative electrode terminals. |
