An electrical line (L) with at least one electrical conductor (1) surrounded by an insulation (2) in which a braid (4) of metallic wires serving for electrical shielding is disposed over the insulation (2), and a jacket (6) of an insulating material is applied over the braid (4). To produce a shield that is effective even at very high frequencies, the insulation (2), which is made of a heat-resistant material, is first covered all around with a closed metallic sheath (3) produced by vapor deposition. The braid (4) is then applied to the sheath (3) in direct contact therewith and, in addition, the braid (4) is covered all around with a metallic coating (5) produced in a coating process.
