Abstract
A catheter includes a tubular inner layer, a reinforcement body disposed around the outer periphery of the inner layer, a protective layer covering the outer periphery of an end of the reinforcement body, and an outer layer covering at least the outer periphery of the protective layer. The protective layer covers the outer periphery of at least one end of reinforcement body, and the end of the reinforcement body covered with the protective layer is buried deeper in a side of the inner layer relative to a portion of the reinforcement body not covered with protective layer. The reinforcement body is prevented from lifting away from the inner layer when the catheter is bent even without increasing the outer diameter of the reinforcement body.
