PROBLEM TO BE SOLVED: To provide a compact coaxial cable that is excellent in plating adhesion and has an excellent high-frequency characteristic. SOLUTION: An insulation 2 made of a fluorine resin on a conductor 1, an ABS resin film layer 3 on the insulation 2, an electrodeless-plated metal layer 4 on the ABS resin film layer 3, an electroplated metal layer 5 on the electrodeless-plated metal layer 4 and a protective covering layer 6 on the outermost layer are formed. For this coaxial cable, the adhesion strength of the plating is enhanced by interposing the ABS resin film layer 3 between the insulation 2 of which surface is modified and the plated layer 4, so that the durability of the plating can be improved. The ABS resin film layer 3 is an extremely thin layer and does not affect a high-frequency characteristic, so that an excellent high-frequency characteristic can be provided. Additionally, because the coaxial cable does not use metal braiding and is composed of the plated metal layers, the fine diameter of the coaxial cable can be realized.
