The present invention relates to the technical field of cables, and provides a submarine cable. The submarine cable comprises multiple core wires which are twisted together; the core wires each comprises a first metal wire and a conductive layer wrapping the first metal wire; and the conductivity of the conductive layer is greater than the conductivity of the first metal wire. By means of the described setting, when the submarine cable is electrified by alternating current, the current concentrated on the surface part of the first metal wire is partially transmitted to the conductive layer to improve the current carrying capacity of the surface part of the first metal wire, such that the alternating current resistance of the first metal wire is reduced, thereby reducing the electric energy loss. La présente invention se rapporte au domaine technique des câbles et concerne un câble sous-marin. Le câble sous-marin comprend de multiples fils d'âme qui sont torsadés ensemble ; les fils d'âme comprenant chacun un
