Stranded wire

A stranded wire having a plurality of steel wires twisted together, comprising:

• in a cross section perpendicular to a longitudinal direction,
• a central wire as the steel wire;
• a plurality of first circumferential wires as the steel wires arranged in contact with the central wire to surround an outer periphery side of the central wire;
• and
• a plurality of second circumferential wires as the steel wires arranged in contact with the first circumferential wires to surround an outer periphery side of a region where the first circumferential wires are arranged, the second circumferential wires being greater in yield stress than the central wire and the first circumferential wires;
• the central wire being in surface contact with the first circumferential wires,
• the first circumferential wires being in surface contact with the second circumferential wires,
• in the cross section perpendicular to the longitudinal direction,
• a region on an outer periphery of a respective one of the plurality of first circumferential wires that is in contact with the central wire being 5% or more and 10% or less of the outer periphery,
• a region on an outer periphery of a respective one of the plurality of first circumferential wires that is in contact with one of the plurality of second circumferential wires being 5% or more and 10% or less of the outer periphery.
