<p>PROBLEM TO BE SOLVED: To provide a medical guide wire capable of accurately and quickly mounting a coil spring to a predetermined position of a distal end side small-diameter part of a core wire in manufacture.SOLUTION: A medical guide wire includes: a core wire 10 having a proximal end side large-diameter part 11, a distal end side small-diameter part 13 and a step part 12; and a coil spring 20 mounted to the outer periphery of the distal end side small-diameter part of the core wire in the axial direction. With the rear end 22 of the coil spring abutted on the step part 12 of the core wire, at least the tip part and the rear end part of the coil spring is fixed to the distal end side small-diameter part of the core wire, and a round surface 121 is formed between the distal end side small-diameter part and the step part of the core wire.</p> |
