Highly-flexible miniature coaxial line

A highly-flexible miniature coaxial line, preferably for connection to test sets, having extremely low capacitance fluctuation when the line is moved. The aim of the invention is to prevent movement artefacts and to provide a highly-flexible miniature coaxial line having good serviceability characteristics. The invention is based on the object of creating a coaxial line which is highly flexible, proof against fracture and of a small diameter, and which has extremely low capacitance fluctuations between the inner conductor and the screen during movement. This is achieved in that a closely fitting elastic and electrically conductive layer is extruded directly onto the outer conductor, the modulus of elasticity of which layer is less by the factor 0.2 than that of the dielectric which is arranged around the inner braided conductor, and in that an external, insulating outer sleeve is extruded onto the layer. The layer has a specific internal insulation resistance of rho D
