Earthing is an important technology in the fields of electric power, communication，and lightning protection. The earthing electrode is used as the ground and the electric terminal which comes in various shapes from small scale like rod-shaped and plate-shaped to large scale such as ring-shaped，mesh-shaped etc. When designing earthing，its resistance which is an index of the rise in electric potential must be known. The accurate analytic solution of the earthing resistance excepted for the electrode of the special form such as a rotating ellipsoid electrode cannot be obtained. The earthing resistance of the electrode such as a rod-shaped and a plate-shaped is computed by approximated analysis. There are methods of earthing simulation such as the tank model method or Laplace numerical analysis equation method （for example，the finite element method）used to estimate a shaped earthing resistance without analytic answer. This paper discusses the results of examining；comparing and analyzing the earthing resistance produced using the shape factor method which focuses on the shape of the earthing electrode.
