Provided is a guide wire including a core shaft, a coil body wound around the core shaft, a distal-end joining region to which a distal end of the core shaft and a distal end of the coil body are joined, and a proximal-end joining region to which a proximal end of the core shaft and a proximal end of the coil body are joined, in which the coil body has a sparsely wound portion having a relatively sparse coil pitch, the sparsely wound portion being disposed between the distal-end joining region and the proximal-end joining region.
