Abstract
A grounding conductor 1 is composed of a conductive metal portion 2 and a conductive casing portion 3 that covers the conductive metal portion 2. The conductive casing portion 3 has a specific resistance of 0.01 to 0. (.OMEGA.m). Since the grounding conductor 1 is composed of the conductive metal portion 2 and the conductive casing portion 3 that covers the conductive metal portion 2, the conductive metal portion 2 is connected to the earth via the conductive casing portion 3. The conductive metal portion 2 does not contact directly with the earth but is electrically connected to the earth via the conductive casing portion 3. This prevents the conductive metal portion 2 from being corroded. It is also possible to avoid a disconnection in the conductive metal portion 2.
