Abstract: A metallic cable includes, in order from an inner side thereof, a plurality of coated conduction wires, a press winding tape, a laminated tape, and an outer jacket. The outer jacket is provided on an outer circumference of the laminated tape and such that it covers the outer circumference of the laminated tape. The outer jacket is made of polyethylene having a density greater than or equal to that of medium-density polyethylene (MDPE) (≥930 kg/m3), and more preferably made of high-density polyethylene (≥942 kg/m3). If polyethylene having a density that is equal to or greater than that of MDPE is used to form the outer jacket, the temperature that is appropriate for extruding MDPE approaches a bonding temperature range of the resin layer of the laminated tape. The resin layer and the metal layer can be bonded and joined together at an overlapped part, tightly enclosing a cable core.
