Abstract
A guide wire includes a wire member having a first wire disposed on the distal side of the guide wire, and a second wire disposed on the proximal side from the first wire. The second wire is made from a material having an elastic modulus larger than that of the first wire. For example, the first wire is made from a superelastic alloy, and the second wire is made from a stainless steel. The first wire is joined to the second wire at a welded portion by welding. A coil is disposed on the distal side from the first wire. A cover layer is formed on the outer peripheral surface of the wire member in such a manner as to cover at least the welded portion. The cover layer is made from a material capable of reducing the friction of the cover layer, for example, a fluorocarbon resin or a hydrophilic material, to thereby improve the sliding performance of the guide wire. Such a guide wire is excellent in operationality and kink resistance.
