Abstract
A guidewire includes a shaft, an outer coil wound around a distal end portion of the shaft, and an inner coil provided within the outer coil. The outer coil is formed by winding a plurality of stranded wires in a spiral manner, each of the stranded wires being formed of a plurality of elemental wires twisted together, and the direction of winding of the outer coil is opposite to the direction of winding of the inner coil.

A guidewire comprising:
- a shaft,
- an outer coil wound around a distal end portion of the shaft,
- an inner coil provided within the outer coil, the inner coil being formed of a plurality of first stranded wires wound in a spiral manner such that each first stranded wire is formed of a plurality of first elemental wires twisted together, and
- a distal end bonding member that fixes a distal end of the outer coil to a distal end of the shaft and that bonds a distal end of the inner coil to the distal end of the shaft,
- wherein the outer coil is formed of a plurality of second stranded wires wound in a spiral manner, each of the second stranded wires being formed of a plurality of second elemental wires twisted together, and
- a winding direction of the outer coil is opposite to a winding direction of the inner coil.
