ABSTRACT:
A core wire of a guide wire has a plurality of twisted thin threads, a distal end of the core wire being diametrically reduced to be a thinnest tip, which has twisted ends united together. A resin layer is coated on the outer surface of the core wire. The thinnest tip of the leading end of the core wire is squelched into a flat-shaped configuration so as to form a flat portion. The flat portion is shaped into a multiple-stepped structure in which the thickness of the flat portion is progressively reduced by three steps or more in approaching the distal end of the core wire.
