Provided is a cable having improved durability while enabling smooth bending operation. A cable formed by covering a conductor section, in which a conductor is spirally disposed in a longitudinal direction, with an insulating covering member having an insulating property includes: a conductor section formed by stranding a plurality of bare wires to form a core wire and arranging a plurality of the core wires closely in contact in an annular shape; and a reinforcement section including a cord that includes a plurality of filaments of a fiber material, and formed by compressing and housing the cord substantially linearly within a central space formed by the core wires in the annular shape in the conductor section, and the cord is press-fitted into the central space.

Cable

An aluminium-based conductive material used in a driving part of robots or various devices and used, for example, in a wiring that is loaded with cyclic bending, as well as an electric wire and a cable using the same, contains 0.1 to 1.0 mass % of scandium and further contains, as a rest part, aluminium and unavoidable impure substances and is formed of a metal texturehaving crystal grainswith an average grain size of 2 &#x3bc;m or less and aluminium-scandium series nanoprecipitates generated in a grain boundaryof the crystal grains. Further, it is preferable that the metal texturecontains the crystal grainsof 1 &#x3bc;m or less at a cross sectional ratio of 15% or more.
