A guide wire includes a core shaft and a coil body covering an outer surface of a distal portion of the core shaft. The coil body includes a straight section that extends in a straight state from a proximal end of the coil body toward a distal end of the coil body, and a bent section arranged at a distal end of the straight section. The coil body may be formed by winding at least one element wire into a helical coil structure, or by winding a plurality of stranded wires (obtained by stranding a plurality of element wires) into a helical coil structure. The element wires and/or the stranded wires of the coiled body are in contact with each other on a side of the bent section opposite to a side toward which the bent section is bent relative to an axial direction of the straight section.
