An aluminum alloy wire material, which has an alloy composition containing: 0.1 to 0.4 mass % of Fe, 0.1 to 0.3 mass % of Cu, 0.02 to 0.2 mass % of Mg, and 0.02 to 0.2 mass % of Si, and further containing 0.001 to 0.01 mass % of Ti and V in total, with the balance being Al and unavoidable impurities, in which a grain size is 5 to 25 μm in a vertical cross-section in a wire-drawing direction thereof, and an average creep rate between 1 and 100 hours is 1×10−3 (%/hour) or less by a creep test under a 20% load of a 0.2% yield strength at 150° C.
