PROBLEM TO BE SOLVED: To provide a guide wire capable of surely securing a radiopacity by X-rays, and surely recognizing the degree of an insertion depth when inserting the guide wire to a target part of a lumen of a living body.
SOLUTION: The guide wire 1 has a wire body 2 and a radiopaque part 7 formed at its distal end. The radiopaque part 7 has a coil 6 composed of a metallic material and provided on the outer periphery of the wire body 2, and a coating layer 5 which covers the coil 6 and to which a radiopaque medium is added, and is divided into a first radiopaque region 71, a second radiopaque region 72, and a third radiopaque region 73. The radiopacity is lower in the second radiopaque region 72 than in the first radiopaque region 71. Such a difference in the radiopacity is caused by the followings: the helical pitch of the coil 6 in the second radiopaque region 72 is smaller than that in the first radiopaque region and the content of the contrast medium in the coating layer 5 in the second radiopaque region 72 is less than that in the first radiopaque region 71.
