摘要

PROBLEM TO BE SOLVED: To provide a ground rod which reduces grounding resistance with an inexpensive means while considering environment. SOLUTION: Each end of a plurality of electrical wires 6a and 6b is connected to the periphery of a ground rod 1 as a conductor, so that the area of the conductor contacting with soil increases when the ground rod is laid underground in soil.
