Abstract
The tube is stretchable. The tube is stretched by applying tension in a longitudinal direction. The tube returns to its short state by releasing the above-described tension applied in the longitudinal direction. A plurality of protrusions are formed on an inner surface of the tube. Each of the plurality of protrusions extends in a circumferential direction. The plurality of protrusions are arranged side by side in the longitudinal direction of the tube. A pitch of the protrusions is less than or equal to 1.5 μm.
