A concentric stranded conductor having a concentric strand having multiple strands. Each strand has multiple single wires. The concentric stranded conductor has a central core strand (5) and a first concentric strand layer (11) having multiple first-layer strands (9) twisted around the central core strand. The twist pitch of the central core strand is from 8 to 70 times the distance between diametrically opposed outer wires of the central core strand, the twist pitch of the first concentric strand layer is from 8 to 30 times the distance between diametrically opposed strands of the first concentric strand layer. |α−(β+γ)| is 15 degrees or less, where α is the twist angle of the central core strand and β and γ are the twist angles of the first-layer strands and first concentric strand layer, and the single wires are made of an aluminum or aluminum alloy to have elongation of 2% or more.
