Abstract: PROBLEM TO BE SOLVED: To provide a communication tube capable of effectively using the inside space of a communication tunnel. SOLUTION: The communication tube 20 is provided inside a communication tunnel, inside which a communication cable is arranged. The communication tube 20 is split along the longitudinal direction so as to form a plurality of split bodies 22. Respective split bodies 22 are provided with a combining groove section 30 on one side in the longitudinal direction and combining protrusion 40 on the other side. The combination of a plurality of split bodies 22 forms a communication tube 20. The split body can be kept and moved in such a state as is wounded on a bobbin having a small diameter, which leads to easy movement and less space required for storage. A projected part on the outside surface of the communication tube 20 entraps into the gap between a plurality of communication tubes 20 when arranging the plurality of communication tube 20, whereby space occupied by projected part can be minimized. As a result, relatively a number of communication tubes can be provided inside the communication tunnel.
