ABSTRACT:
The present invention relates to a grounding device in which a grounding member E having a grounding conductor2and a conductive laminated portion5covering the grounding conductor2is 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.
