Claim:
1. A negative electrode terminal for a lithium ion battery, made of a clad material comprising: a first metal layer made of Al or an Al alloy; a second metal layer made of Cu or a Cu alloy disposed under the first metal layer; and a reaction-suppressing layer interposed between the first metal layer and the second metal layer, wherein the reaction-suppressing layer suppresses a reaction between the first metal layer and the second metal layer, and wherein the first metal layer has a thickness larger than a sum of thicknesses of the second metal layer and the reaction-suppressing layer, the thickness of the first metal layer is uniform, the thickness of the second metal layer is uniform, the thickness of the reaction-suppressing layer is uniform, and the thicknesses are in a direction in which the first metal layer, the second metal layer, and the reaction-suppressing layer are stacked.
