Abstract
A first tube is a medical tube provided with a first portion, a second portion and a third portion in this order from the proximal end side toward the distal end side and is made of a resin. At the second portion, the outer diameter is smaller than the outer diameter of the first portion and the inner diameter is substantially equal to the inner diameter of the first portion. At the third portion, the outer diameter and the inner diameter are respectively smaller than the outer diameter and the inner diameter of the second portion. In this manner, a medical tube in which the outer diameter of the proximal end side is relatively large and the outer diameter of the distal end side is relatively small while securing the inner diameter having a sufficient size at the distal end side can be provided.
