The present invention relates to a downtown grounding rod, having a rod-shaped ground rod body 10 having an outer diameter of 30 mm, and having a conical entry portion 11 formed at a lower end of the ground rod body 10, wherein the ground rod body ( 10) The structure of the ground electrode accommodating part 12 for accommodating the ground electrode 30 is formed at the upper end of the structure, and thus the construction cost and material cost can be reduced by reducing the amount of the ground electrode laid, and the road restoration work cost can be reduced by reducing the excavation area when the ground electrode is laid. It can reduce the fluctuations in ground resistance due to changes in external environment such as soil quality, moisture, and use, reduce the fluctuations in ground resistance due to biennial changes, and do not use earth reducer. Soil pollution can be prevented.
