点がある。In this case, since the amount of current flowing between the aluminum of the anode and the copper of the anode is the same, the greater the area ratio of copper to the area of aluminum, the greater the current density on the aluminum surface and the greater the amount of corrosion thereof. . Therefore, when the aluminum conductor 2 is connected to the copper conductor 1, the area of copper with respect to aluminum on the exposed surface 3 becomes large, the amount of corrosion of aluminum becomes large, and cavities are easily generated, and electrolyte solution such as rainwater stays therein. There are drawbacks that the recesses are easily and gradually deepened, the electric resistance of the copper-clad copper 4 and the aluminum portion 5 is increased, and the copper-clad copper 4 is peeled off.
