A weld is formed over the entire crimp surface of the wire connection portion, the conductor portion, and the conductor portions, so that the gap is collapsed and the wire connection portion, the conductor portion, and the conductor portions are integrated, and
There is no risk that the crimp force of the electrical connection will decrease over time, and since the conductor is protected by the weld, it is protected from oxidation and other corrosion, so high electrical performance can be maintained for a long period of time.
