A guidewire in which a surface of a coil body is covered with a coating portion and the coil body (guidewire) can be easily curved is provided. In a coil-type guidewire (1), a coating portion (10) is formed by stacking a plurality of films (10a, 10b), a lowermost layer film (10a) of the coating portion (10) is arranged to come between wires (7) of the coil body (6), and a void (20) is formed between the lowermost layer film. and a film (10b) disposed above the lowermost layer film. By forming such a void (20), it is possible to make the coating portion (10) easily bent and to improve flexibility of the coating portion (10). As a result, it is possible to provide the guidewire (1) in which the coil body (6) is covered with the coating portion (10) and the coil body (6) (the guidewire (1)) can be easily curved. |
