Abstract
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 μm 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 μm or less at a cross sectional ratio of 15% or more.
