Abstract:
1. A negative-electrode terminal for a cell comprising a clad portion formed by bonding a first metal layer made of Al or an Al alloy and a second metal layer containing Ni and Cu and consisting of one or a plurality of layers to each other, wherein the first metal layer includes a connected region connected with a cell terminal connecting plate for connecting cell terminals of a plurality of cells with each other and a stacked region adjacent to the connected region on the side of the same surface the second metal layer is bonded to the first metal layer in the stacked region, and configured to be connectable to cell negative electrodes of the cells, and the second metal layer is stacked on the first metal layer in the stacked region which is separate from the connected region, in a direction in which the cell negative electrodes extend.
