PROBLEM TO BE SOLVED: To provide a biological adhesive tube which is reduced in the influence on a living organism and thus has improved safety.SOLUTION: The biological adhesive tube 10 has: a tube shape substrate 12 formed of a biocompatible material and a plurality of projections 13 formed of a biocompatible material and configured so as to protrude from the outer circumferential surface of the substrate 12. The biological adhesive tube 10 is bonded to living tissues by the van der Waals force by causing the plurality of projections 13 to be in contact with the living tissues.
