A high-frequency coaxial cable has a multi-layer insulation made of polymeric materials surrounding a central conductor and having an electrical shielding enclosing the insulation. The individual layers of the insulation are of fluoropolymers, with at least a first layer (2) that encloses the central conductor (1) being made of a fluoropolymer capable of being formed from a melt and an outer second layer (3) being made of a fluoropolymer not formable from a melt. In this cable, the second layer (3) is porous and is inter-engagedly connected with the surrounding shield (4).
