Claim:
1. A guide wire comprising: an elongated wire body having flexibility; a distal side coating layer that covers a distal portion of the wire body and is made of a resin material; a cylindrical member that has an outer diameter substantially the same as an outer diameter of a proximal portion of the distal side coating layer, that encircles a portion of the wire body and that has a distal portion positioned proximate the proximal portion of the distal side coating layer; and a joint member that is disposed at a proximal side of the cylindrical member and joins the cylindrical member and the wire body, wherein the joint member has a gradually decreasing outer diameter portion whose outer peripheral surface has a diameter which gradually decreases toward a proximal side of the wire body, wherein a proximal portion of the cylindrical member has a gradually decreasing outer diameter portion whose outer peripheral surface has a diameter which gradually decreases toward the proximal side of the wire body, and wherein the outer peripheral surface of the gradually decreasing outer diameter portion of the proximal portion is continuous with the outer peripheral surface of the gradually decreasing outer diameter portion of the joint member at respective parts of the outer peripheral surfaces whose diameters decrease at a same rate.
