To provide a very simple economical grounding apparatus having a prescribed low ground resistance by joining a large-area contact surface to the side of an existing structural body which has a large-area contact to the ground, and by connecting the ground electrode underground to a connection body.

A ground apparatus comprises a structural body 1, that is at least partially buried underground and a ground electrode 3 that is buried underground, wherein the structural body and the ground electrode are connected underground, while at the same time, the article to be grounded 5 is connected to the ground electrode.
