Abstract
A guide wire is provided with a core shaft, a coil portion, a sound source, and wiring. The coil portion is coupled to a distal end portion of the core shaft and is helically wound around a periphery of the core shaft to the rearward. The coil portion includes an open portion in which an interval of element wires constituting the coil portion itself is larger than that in another portion. The sound source is provided in an inner side of the open portion. The wiring extends along an extending direction of the core shaft, and a distal end of the wiring is positioned at an inner side of the coil portion. The wiring supplies energy to the sound source.
