Abstract
In a guide wire of the present invention, a distal end portion of a core has a distal small-diameter body and a combined truncated cone including a first truncated cone in order from a distal end side to a proximal end side. A twist angle of the distal small-diameter body is specified to be larger than the twist angle of the first truncated cone to increase flexibility for easily bending at the distal end. At least one truncated cone is connected on the proximal end side of the first truncated cone to form the structure of a combined truncated cone. Thus, the guide wire of the present invention has high rotation transmission performance toward the distal end side and other performances. Accordingly, the guide wire can be quickly reached to the vascular lesion and has high passability at the vascular lesion.
