Abstract
A catheter includes an inner layer, a reinforcement layer at least partially inside the inner layer or on an outer periphery of the inner layer, and an outer layer covering the inner layer and the reinforcement layer. The reinforcement layer has a wire wound so that a gap is present between adjacent portions of the wire. The inner layer has an uneven outer peripheral surface on which a protruded portion is formed in a location of the wire, and in which a depressed portion is formed in a location of the gap. The outer layer has a protrusion part that extends into the depressed portion of the inner layer, the protrusion part entering deeper than the reinforcement layer through the gap and extending in an axial direction of the catheter. The outer layer is not easily detached from the inner layer.
