An aluminum (Al) alloy wire, which is an extra fine wire having a wire diameter of 0.5 mm or less, contains, in mass%, Mg at 0.03% to 1.5%, Si at 0.02% to 2.0%, at least one element selected from Cu, Fe, Cr, Mn and Zr at a total of 0.1% to 1.0% and the balance being Al and impurities, and has an electrical conductivity of 40% IACS or more, a tensile strength of 150 MPa or more, and an elongation of 5% or more. By producing the extra fine wire from an Al alloy of a specific composition containing Zr, Mn and other specific elements, though the extra fine wire is extra fine, it has a fine structure with a maximum grain size of 50 µm or less and is superior in elongation. A tensile strength after being retained for 1000 hours at an arbitrary temperature selected from 80°C to 150°C is 150 MPa or more, which is superior in heat resistance. Thereby, there is provided an Al alloy wire which is extra fine and superior in elongation while having a high strength and a high electrical conductivity, an Al alloy twisted wire, a covered electrical wire including the Al alloy wire or the Al alloy twisted wire, and a wire harness including the covered electrical wire.
