Abstract
A layered stranded conductor has an inner layer section and an outer layer section. The inner layer section has one or more inner section element wires, including a first element wire having an outer diameter of 0.08 mm or less. The outer layer section has one or more outer section element wires, including a second element wire stranded with the first element wire and an outer diameter of 0.08 mm or less. The first element wire has 1.5 times or higher tensile strength than that of a second element wire. Additionally, the one or more inner and the one or more outer section element wires are stranded with each other such that a ratio of a strength of the one or more inner section wires to a strength of the one or more outer section wires is 0.5 to 5.
