A guide wire includes a coil body composed of a proximal-end coil and a distal-end coil connected to each other at a connecting portion in a manner that secures alignment of the two coils and sufficient penetration of a brazing metal into the connecting portion of the coils. The distal-end coil is formed of a first wire that is coiled, and the proximal-end coil is formed of a second wire that is coiled. The distal-end coil and the proximal-end coil are connected to each other with alternately disposed windings of the first wire and the second wire. Furthermore, the connecting portion of the coil body includes a gap. In this manner, the central axes of the two coils can be easily kept aligned with each other even before brazing, and a brazing metal or the like can easily penetrate into the connecting portion.
