An aluminum alloy element wire has a chemical composition including in mass percent: Mg: 0.3% or more and 0.9% or less, Si: 0.1% or more and 0.7% or less, Fe: 0.1% or more and 0.4% or less, at least one element selected from the group consisting of Cu, Cr, Ni, and Zr: 0.01% or more and 0.5% or less in total, and the balance being Al and unavoidable impurities. The aluminum alloy element wire has a surface roughness Ra in the range of 0.15 μm or more and 2 μm or less as measured with a non-contact surface roughness measuring machine. An aluminum alloy stranded wire includes a plurality of the aluminum alloy element wires twisted together. An automotive electric wire includes the aluminum alloy stranded wire. A wire harness includes the automotive electric wire, and a terminal crimped to the aluminum alloy stranded wire of the automotive electric wire.
