PROBLEM TO BE SOLVED: To provide a guide wire enabling a user to reliably recognize that an insertion operation is performed when the guide wire is inserted into a lower limb blood vessel of a left leg through a lower limb blood vessel on a right leg by using, for example, a Cross Over method.SOLUTION: The guide wire 1 includes a long wire body 2 having flexibility, and a resin coating layer 6 which covers the distal end of the wire body 2 and is made of a resin material. The guide wire 1 further includes a cylindrical member 7 which is inserted into the wire body 2 and positioned at the base end side of the resin coating layer 6. The cylindrical member 7 has a plurality of protrusions 72 formed to protrude on the outer periphery of the member 7. In viewing the guide wire 1 from the distal end side, the protrusions 72 is each such that an apex 721 protrudes to be higher than the outer periphery 64 of the resin coating layer 6.COPYRIGHT: (C)2013,JPO&INPIT【課題】例えばCross Over法により、右脚にある下肢血管から左脚にある下肢血管へガイドワイヤを押し込む際に、その押込操作が行なわれているのを確実に把握することができるガイドワイヤを提供すること。【解決手段】ガイドワイヤ1は、可撓性を有する長尺なワイヤ本体2と、ワイヤ本体2の先端部を覆い、樹脂材料で構成された樹脂被覆層6とを備える。このガイドワイヤ1は、ワイヤ本体2に挿通され、樹脂被覆層6の基端側に位置する筒状部材7をさらに備え、筒状部材7は、その外周部に突出形成された複数の突部72を有し、ガイドワイヤ1を先端側から見たとき、各突部72は、それぞれ、その少なくとも頂部721が樹脂被覆層6の外周部64よりも突出している。【選択図】図1
