PURPOSE: An environmentally-friendly grounding device for completely discharging an impact current is provided to prevent a function loss due to a gap between a ground rod and a discharge probe. CONSTITUTION: Each discharge prove(20) is combined with a ground rod(10). A pressure part of each discharge probe is contacted with the outer side of the ground rod by pressurization of a round jig. An autogenous welding unit is formed on the upper and lower sides of the pressure unit by a TIG welding with the outer side of the ground rod. A moisture inlet(11) is formed around the upper side of the ground rod. A moisture outlet(12) is formed around the lower side of the ground rod.
