Abstract
An aluminum alloy contains equal to or more than 0.005 mass % and equal to or less than 2.2 mass % of Fe, and a remainder of Al and an inevitable impurity. In a transverse section of the aluminum alloy wire, a surface-layer void measurement region in a shape of a rectangle having a short side length of 30 μm and a long side length of 50 μm is defined within a surface layer region extending from a surface of the aluminum alloy wire by 30 μm in a depth direction, and a total cross-sectional area of voids in the surface-layer void measurement region is equal to or less than 2 μm2.
