The invention, which relates to the technical field of through-the-earth communication, discloses a through-the-earth communication low-impedance buried electrode comprising a wire, a compression nut, a sleeve, an AgCl electrode and a buried electrode tube. One end of the wire is connected with the AgCl electrode, the other end of the wire sequentially penetrates through the sleeve and the compression nut to be led out, the AgCl electrode and the sleeve are fastened and sealed in a threaded mode, the compression nut and the buried electrode tube are fastened in a threaded mode, and the AgCl electrode is soaked in saline water filled in the buried electrode tube; wherein a shaft shoulder step is arranged at the upper end of the sleeve and plays a limiting role in downward pressing of the pressing nut; the electrode can reduce the contact impedance between the buried electrode and the ground, and the AgCl electrode is applied to land survey and has the characteristics of high repeated utilization ...
