Guidewire having high safety and improved flexibility and rotation followability. This guidewire has an inner coil (50) that surrounds a distal side (30) portion of a core shaft (14), and an outer coil (60) that surrounds the inner coil and the distal side portion of the core shaft. A front end of the outer coil and a front end of the inner coil are joined to a tip of the core shaft by a tip plug (15). Further, the guidewire has a coil joint that joins only the outer coil and the inner coil to each other. With this configuration, the flexibility of the inner coil is maintained. Moreover, rotation of a proximal side of the guidewire is transmitted to the inner coil not only from the core shaft but also from the outer coil. This leads to improvement in rotation followability.
