PROBLEM TO BE SOLVED: To provide a medical tube with high flexibility, kink resistance and tensile strength.
SOLUTION: The medical tube includes at least a reinforcement layer and an outer layer. The reinforcement layer includes a first reinforcement layer and a second reinforcement layer located outside the first reinforcement layer. The first reinforcement layer is a coil made of at least one strand wire wound in a direction, and the second reinforcement layer is a coil made of at least one wire wound in another direction differing from and indifferent to the first reinforcement coil. The coil making the second reinforcement layer is characterized in that it is wound with a larger pitch over the entire region where the second reinforcement layer is present than the coil making the first reinforcement layer, and at a winding angle between 13° or more and 79° or less relative to the tube axial direction.
