Abstract
An aluminum alloy wire is composed of an aluminum alloy. The 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 crystallization measurement region in a shape of a rectangle having a short side length of 50 μm and a long side length of 75 μm is defined within a surface layer region extending from a surface of the aluminum alloy wire by 50 μm in a depth direction, and an average area of crystallized materials in the surface-layer crystallization measurement region is equal to or more than 0.05 μmand equal to or less than 3 μm.
