A guidewire (10) include a first junction (11) that joins together a distal end of an inner coil body (60) and a portion of a core shaft (20) positioned away from a distal end toward a proximal end a second junction (12) that joins a proximal end of the inner coil body (60) and the core shaft (20) together a third junction (13) that joins a distal end of the outer coil body (50) and the distal end of the core shaft (20) together and a fourth junction (14) that joins a proximal end of the outer coil body (50) and the core shaft (20) together. The outer coil body (50) includes a tapered coil portion (52) and a uniform-diameter coil portion (53). The inner coil body (60) is disposed inside the uniform-diameter coil portion (53) of the outer coil body (50). The inner coil body (60) is joined to the core shaft (20) at only the first junction (11) and the second junction (12) but not joined to the outer coil body (50).
