PURPOSE:To prevent corrosion at a contact part of a core wire and an external layer by providing an anti-corrosive compound in a space between a core wire to form a conducting body for an electric current and a conductive external layer to cover this core wire. CONSTITUTION:A conductive body for an electric current consists of a core wire 1 and a conductive external layer 3 to cover along the core wire 1 and a periphery of the external layer 3 is insulated by an insulator 4 except a part 3a to become a sliding face. In a space with the external layer 3 of the periphery of the core wire 1, an anti-corrosive compound is filled. This construction permits to seal the above space completely even if the sealing by the external layer 3 is incomplete and to prevent water from coming in at a contact part of the core wire 1 and the external layer 3, so that the corrosion of the contact part can be prevented. |
