Provided is a guide wire, which comprises a lengthy wire body, and a marker disposed in at least the tip side portion of the wire body all over the circumference and having a function to indicate the position of the wire body in a living body. The marker is formed into a lattice shape as a whole by causing a first filament portion and a second filament portion to intersect with each other at a plurality of portions. Moreover, the intersecting portions of the first filament portion and the second filament portion are formed in plurality in the marker. Noting a predetermined one of those intersecting portions, therefore, the predetermined intersecting portion looks, as if it moves radially of the guide wire, when the guide wire is turned on its axis. Thus, it is possible to confirm reliably that the guide wire has been turned.

L'invention porte sur un fil de guidage, qui comprend un corps de fil longitudinal, et un marqueur disposé dans au moins la partie côté extrémité du corps de fil sur toute la périphérie et ayant une fonction pour indiquer la position du corps de fil dans un corps vivant. Le marqueur est formé globalement selon une forme de maillage, en amenant une première partie de filament et une seconde partie de filament à se couper entre elles au niveau d'une pluralité de parties. De plus, les parties d'intersection de la première partie de filament et de la seconde partie de filament sont formées en pluralité dans le marqueur. Si l'on note l'une prédéterminée de ces parties d'intersection, par conséquent, la partie d'intersection prédéterminée semble se déplacer radialement par rapport au fil de guidage, lorsque le fil de guidage est tourné sur son axe. Ainsi, il est possible de confirmer de façon fiable que le fil de guidage a été tourné.
