Provided is a guide wire: with which the position of the tip of the guide wire can be clearly visualized in either X-ray imaging or ultrasound imaging; and which does not kink easily and does not easily damage the medical tube disposed on the outside of the guide wire. Said guide wire (10) comprises: a core wire (20), the diameter of the tip (23) of which has been reduced; an X-ray-impermeable X-ray marker (30) fitted on the tip (23) of the core wire (20); and an ultrasound marker (40) with ultrasound imaging properties that is bonded at a position adjacent to the X-ray marker (30) of the tip (23) of the core wire (20). The ultrasound marker (40) has a form in which large diameter sections (43) are provided so as to alternate successively along the axial direction of the core wire (20) with small diameter sections (45) having a smaller diameter than that of the large diameter sections. The outer diameters of the X-ray marker (30) and the ultrasound marker (40) in the area where the two are bonded differ from each other. |
