Abstract: The present invention relates to a grounding device in which a grounding member E having a grounding conductor 2 and a conductive laminated portion 5 covering the grounding conductor 2 is integrated with a foundation member B of a building so that the grounding member E and the foundation member B overlap partly or entirely. The grounding device is configured so that the grounding member having the grounding conductor and the conductive laminated portion covering the grounding conductor is integrated with the foundation member of the building are so that the grounding member and the foundation member overlap partly or entirely. This makes it possible to easily offer a small grounding resistance. Further, the foundation member of the building contacts the earth over a large area. This enables a small grounding resistance to be stably offered for a long period.

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. (?·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.
