Patent abstract
In a coil-type guidewire, a coating portion of the coil portion is formed by stacking a plurality of films. An innermost film of the coating portion is arranged to come between adjacent coils of the coil body, and voids are formed between the innermost film and a film disposed outside of the innermost film. By forming such voids, it is possible to easily bend the coating portion and to improve flexibility of the coating portion. As a result, the guidewire in which the coil body is covered with the coating portion and the coil body (the guidewire) can be easily curved.
