Claim:
An overhead cable comprising a plurality of element wires stranded to form a naked stranded cable, which has a cross-sectional shape of an equilateral polygon inscribed in a circle having a diameter of 18.2 mm to 38.4 mm as a fundamental cross-sectional shape, in which adjacent sides of the equilateral polygon intersect with each other at an apex of the equilateral polygon, and two sides of this equilateral polygon that are located at positions farthest from each other are outwardly projected, has two flat-plate-shaped projections corresponding to the two sides, wherein the number of angles of the equilateral polygon is 16 when the diameter of the circle is 18.2 mm, the number of angles is 17 when the diameter is 22 mm, the number of angles is 20 when the diameter is 24.4 mm, the number of angles is 20 or 21 when the diameter is 27.4 mm, the number of angles is 22 when the diameter is 32.6 mm, or the number of angles is 22 when the diameter is 38.4 mm, and a height of the flat-plate-shaped projections is equal to or larger than 0.3 mm and equal to or smaller than 0.75 mm.
