PURPOSE: An expansible cable is provided to maintain a memory action after many times of expansions, and which does not substantially change in electrical attenuation. CONSTITUTION: A cable(100) is provided with a plurality of coaxial cables(110) embedded in a jacket. At least one of a plurality of the coaxial cables is provided with an inside conductor(120), a conductive insulator(130) surrounding the inside conductor(120), and a shield(140) surrounding the conductive insulator(130). It is desirable that one of a plurality of the coaxial cables is further provided with a protecting layer(150) surrounding the shield(140), and the three coaxial cables are embedded in the jacket, and the jacket has Shore hardness of 36D, and the jacket is constructed of material selected from such group that polyester, polyurethane, polyethylene, and a polymer containing polyvinyl chloride.
