Abstract
A guide wire is configured to have a less lossy marker formed at a desired position and providing a relatively high degree of contrastability under X-ray fluoroscopic guidance or the like. The guide wire includes a linear core member, a resin layer covering a main body portion of the core member, and a contrasting portion covering the distal end portion of the core member. The resin layer contains a color developing agent which develops color by laser light irradiation, and a contrast agent composed of a metal oxide powder. The contrasting portion is made from a resin containing a contrast agent composed of a metal powder and has a contrasting function higher than the resin layer. A visible marker is formed on the outer surface of the resin layer through color development of the color developing agent by irradiating the surface of the resin layer with laser light.
