Claim:
1. An aluminum alloy wire to be used as a conductor, containing in mass %: Mg at 0.2% to 1.5%; Si at 0.1% to 2.0%; Fe at 0.1% to 1.0%, or at least one element selected from Cu, Cr, Mn and Zr, and Fe at a total of 0.1% to 1.0%; Ti at 0.005% to 0.08% and B at 0.0005% to 0.016%; Zr at 0.02% to 0.40% and Mn at 0.05% to 0.40%; and the balance being Al and impurities, wherein the content of the Mg is greater than the content of at least one of the Fe, Cu, Cr, Mn, and Zr, wherein the content of the Si is greater than the content of the Fe, and having: an electrical conductivity of 40% IACS or more; a tensile strength of 150 MPa or more; an elongation of 5% or more; a wire diameter of 0.5 mm or less; and a maximum grain size of 50 μm or less, wherein a ratio of the maximum grain size relative to the wire diameter is less than 10%.
