PROBLEM TO BE SOLVED: To provide a ground rod capable of effectively injecting a grounding resistance reducing agent into soil, in consideration for the problem at depth of soil. SOLUTION: The ground rod includes a second cylindrical constituent member 3 to be buried underground for releasing grounding current to the ground. The second cylindrical constituent member 3 is provided with a second flow channel 31 capable of circulating the grounding resistance reducing agent inside for making the grounding current easy to escape to the ground, an outlet hole 22 of a first constituent member 2 for flowing the grounding resistance reducing agent circulating in the second flow channel 31 outside, a blade-type storage part 4 capable of storing part of the grounding resistance reducing agent flowed from the outlet hole 22, and second cylindrical extension parts 32, 33 coupled at end parts of the second constituent member 3.
