<P>PROBLEM TO BE SOLVED: To provide an aluminum alloy having high toughness and high electric conductivity, an aluminum alloy wire, an aluminum alloy twisted wire, a coated electric wire, a wire harness, and to provide a method for producing an aluminum alloy wire. Ž<P>SOLUTION: There is provided an aluminum alloy wire having a composition comprising, by mass, 0.2 to 1.0% Mg, 0.1 to 1.0% Si and 0.1 to 0.5% Cu, and the balance Al with impurities, and satisfying 0.8≤mass ratio (Mg/Si)≤2.7. The Al alloy wire has electric conductivity of ≥58% IACS and elongation of ≥10%. The Al alloy wire is produced through the processes of casting, rolling, wire drawing and softening treatment. By performing the softening treatment, its toughness such as elongation and impact resistance is made excellent, and thus the phenomenon that an electric wire is broken in the vicinity of a terminal part when assembling the wire harness can be reduced.
