Abstract
A catheter includes a shaft, a first wire wound in a spiral shape around an axis of the shaft, and a second wire wound around the shaft in a direction opposite to that of the first wire in a first portion, and wound around the shaft in a direction identical to that of the first wire in a second portion. Accordingly, it is possible to provide a braided structure and the like having flexibility that differs depending on the area in an axial direction.
