Claim Text:
1. An aluminum alloy wire rod having a composition consisting of Mg: 0.10 mass % to 1.00 mass %, Si: 0.10 mass % to 1.00 mass %, Fe: 0.01 mass % to 2.50 mass %, Ti: 0.000 mass % to 0.100 mass %, B: 0.000 mass % to 0.030 mass %, Cu: 0.00 mass % to 1.00 mass %, Ag: 0.00 mass % to 0.50 mass %, Au: 0.00 mass % to 0.50 mass %, Mn: 0.00 mass % to 1.00 mass %, Cr: 0.00 mass % to 1.00 mass %, Zr: 0.00 mass % to 0.50 mass %, Hf: 0.00 mass % to 0.50 mass %, V: 0.00 mass % to 0.50 mass %, Sc: 0.00 mass % to 0.50 mass %, Co: 0.00 mass % to 0.50 mass %, Ni: 0.00 mass % to 0.50 mass %, and the balance: Al and incidental impurities, wherein the aluminum alloy wire rod has an average grain size of 1 μm to 35 μm at an outer peripheral portion thereof, and an average grain size at an inner portion thereof is greater than or equal to 1.1 times the average grain size at the outer peripheral portion.
