<P>PROBLEM TO BE SOLVED: To provide a grounding electrode capable of speedy reduction of grounding resistance by allowing for injection of a grounding resistance reduction agent from the ground surface to the vicinity of the grounding electrode without road excavation. <P>SOLUTION: The grounding electrode comprises: a grounding electrode body 20 obtained by forming at the upper end of a grounding bar 21 a mounting part 22 with a larger diameter than that of the grounding bar 21; and an insulation-coated grounding wire 30 obtained by coating a grounding wire 32 electrically connected to the mounting part 22. The mounting part 22 is vertically perforated with plural outflow holes 23, and the insulation-coated grounding wire 30 internally has a reduction agent supply path 34 communicating with the outflow holes 23, along an axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
