A guide wire includes a core shaft having a distal end portion stepwisely decreasing in diameter, an inner coil body covering at least a part of an outer periphery of the distal end portion, an outer coil body covering an outer periphery of the inner coil body, and a distal end fixing portion that fixes distal ends of the core shaft. The distal end portion includes a small diameter portion, a large diameter portion inside the inner coil body and the outer coil body further in the proximal end direction than the small diameter portion and having a larger diameter than that of the small diameter portion, and a tapered portion that increases in diameter from the small diameter portion toward the large diameter portion. A radiopaque marker is on an outer peripheral surface of the tapered portion. A gap is between the radiopaque marker and the inner coil body.
