Patent ID: 8007447

Claim:
A guide wire comprising: a wire member including a first wire disposed on a distal side of said wire member and a second wire disposed on a proximal side from said first wire, the first wire and the second wire each possessing an end face, the end face of the first wire and the end face of the second wire being welded to one another at a welded portion so that the first and second wires do not axially overlap one another; a cover layer provided on an outer periphery of said wire member and covering said welded portion between said first wire and said second wire; the cover layer is made of a resin material that reduces friction; a proximal-side cover layer disposed on the proximal side from the cover layer without an axial gap between the cover layer and the proximal-side cover layer, the cover layer and the proximal-side cover layer do not axially overlap one another; a distal-side cover layer disposed on the distal side from the cover layer without an axial gap between the cover layer and the distal-side cover layer, the cover layer and the distal-side cover layer do not axially overlap one another; wherein the cover layer is formed such that the wire member is not heated at a time of covering the wire member with the cover layer; and wherein the wire member is directly heated to form the proximal-side cover layer and the distal-side cover layer.
