Electrode used for one pole in underwater transmission of high-voltage direct current, an insulated cable being used for the other pole, such electrodes being adapted to be stationary on the bottom of the sea to serve as the anode and the cathode, respectively, while the sea-water constitutes the electric conductor therebetween. What characterises the invention is that the electrode comprises at least one layer (1) of a flexible, electrically conductive material which preferably is resistant to chlorine-alkali, said layer (1) being enclosed between protective structures (2,3) of a flexible, mechanically resistant material which preferably is resistant to chlorine-alkali, at least one protective structure (2) having openings (4) which are positioned across the surface thereof and through which the sea-water comes into contact with the layer (1).
