PURPOSE: A ground electrode for detecting electric non-resistance is provided to be effectively installed in the ground which forms hard layers. CONSTITUTION: A ground electrode (A) for detecting electric non-resistance comprises a first pipe body (10), a second pipe body (20), a screw member (30), and an opened or closed member (40). The first pipe body is formed with metal and includes a protruded piece (11) at both sides of an upper end unit. The second pipe body fills aqueous solution in the first pipe body. The screw member is combined with a lower end of the first pipe body and includes a vertical flow path (31) or a horizontal flow path. The opened or closed member is combined with the upper end of the first pipe body and blocks the first pipe body from being opened. |
