Abstract
A coil wire rod includes a conductor formed of a conductive material, having a uniform outer peripheral shape, and extending in a direction of an axis. The conductor is divided by a division region having a radial shape around the axis in a cross-sectional view orthogonal to the direction of the axis and includes a plurality of stranded wires each extending in the direction of the axis. The division region is twisted about the axis toward the direction of the axis in at least a part in the direction of the axis.

A coil wire rod, comprising:
- a conductor formed of a conductive material, having a uniform outer peripheral shape, and extending in a direction of an axis, wherein
- the conductor is divided by a division region having a radial shape around the axis in a cross-sectional view orthogonal to the direction of the axis and includes a plurality of stranded wires each extending in the direction of the axis,
- the plurality of stranded wires are annularly arranged side by side in the circumferential direction,
- the division region is a gap between each of the plurality of stranded wires in the circumferential direction, and
- the division region is twisted about the axis toward the direction of the axis in at least a part in the direction of the axis.
