The present invention provides an aluminum alloy wire rod etc. having a high strength and an excellent impact resistance, and used as a wire rod of an electric wiring structure that is less likely to break, and capable of being used for a small-diameter wire. The aluminum alloy wire rod of the present invention has a composition comprising Mg: 0.10 mass% to 1.00 mass%, Si: 0.10 mass% to 1.00 mass%, Fe:0.01 mass% to 1.40 mass%, Ti:0 mass% to 0.100 mass%, B: 0 mass% to 0.030 mass%, Cu: 0 mass% to 1.00 mass%, Ag: 0 mass% to 0.50 mass%, Au: 0 mass% to 0.50 mass%, Mn: 0 mass% to 1.00 mass%, Cr: 0 mass% to 1.00 mass%, Zr: 0 mass% to 0.50 mass%, Hf: 0 mass% to 0.50 mass%, V: 0 mass% to 0.50 mass%, Sc: 0 mass% to 0.50 mass%, Sn: 0 mass% to 0.50 mass%, Co: 0 mass% to 0.50 mass%, Ni: 0 mass% to 0.50 mass%, and the balance: Al and inevitable impurities, wherein a ratio of (standard deviation of crystal grain size of the Al alloy wire rod)/(average crystal grain size of the Al alloy wire rod) is less than or equal to 0.57, and a ratio of (diameter of the Al alloy wire rod)/(average crystal grain size of the Al alloy wire rod) is greater than or equal to 10.
