To provide a bendable unit for multiholed conduit which is excellent in workability, has a little possibility of it being damaged, by receiving the impact force of a pick or the like even if it is buried shallowly, is three-dimensionally bent, and besides provides a small curvature radius.

This is a bendable unit where as many flexible or bendable short pipes 2 as through holes are arranged between at least two multiholed blocks 1 and 1 where a plurality of through holes 3 are made in parallel and both ends of each short pipe 2 are connected impossibly of extraction to the connection ports 4a and 4b of each through hole 3 in the multiholed blocks 1 and 1. This is a bendable unit for a multiholed conduit of such constitution that at least one end of each short pipe 2 is slidable within the connection port 4a. If this unit is bent, one end of the short pipe 2 slides in the connection port 4a, thereby absorbing the compressive force or tensile force working on the short pipe, so it bends in a three-dimensional optional direction with a small curvature radius, conjointly with the short pipe being bendable or flexible.
