Abstract:
The purpose of the present invention is to enhance torque transmission performance while preventing an excessive increase in the rigidity of a proximal portion of a guide wire. This guide wire is provided with a core shaft and a coil body wound around at least a portion of the proximal side of the core shaft. The coil body is bonded to the core shaft with a predetermined bonding means at a position at the proximal end of the core shaft and a first position between the proximal end and the distal end of the core shaft along the axial direction of the guide wire. At at least one specific position in the axial direction in the range from the proximal end to the first position of the core shaft along the axial direction of the guide wire, the coil body is welded to the core shaft.
