Abstract:
A battery terminal is made of a clad material in which a first metal layer made of an Al-based alloy, a second metal layer made of a Cu-based alloy, and a third metal layer made of a Ni-based alloy are bonded to each other in a state where the first metal layer, the second metal layer, and the third metal layer are stacked in this order. The battery terminal includes a shaft portion and a flange portion that radially expands from the shaft portion, and has the third metal layer at least in an end of the shaft portion on a first side in a shaft direction in which the shaft portion extends.
