PROBLEM TO BE SOLVED: To provide an electrode device in which resonance is possible under a wide range of environments.SOLUTION: An electrode device is an electrode device used as an auxiliary electrode for measuring ground resistance and includes: an electrode sheet 11 having conductivity; and an inductor 13 that is provided on the electrode sheet 11 and is connected to the electrode sheet 11. A contact area of the electrode sheet 11 facing the earth is changeable. Accordingly, when measurement of ground resistance is performed by using the electrode sheet 11 as an auxiliary electrode, a contact area of the auxiliary electrode facing the earth can be adjusted by changing the contact area of the electrode sheet 11 facing the earth. |
