Abstract
A guide wire includes an elongated wire body having flexibility; a distal member that covers a distal portion of the wire body and is configured to have a resin material; and a hydrophilic lubricant layer that is formed so as to cover a proximal end of the distal member and is configured to have a hydrophilic material. In addition, the hydrophilic lubricant layer has a tapered shape whose outer diameter gradually decreases toward a proximal side. In addition, the maximum outer diameter of the hydrophilic lubricant layer is smaller than the maximum outer diameter of the distal member. In addition, a proximal portion of the distal member has a tapered shape whose outer diameter gradually decreases toward the proximal side, and a distal end of the hydrophilic lubricant layer is positioned at the tapered portion of the distal member.
