Abstract: PROBLEM TO BE SOLVED: To provide a high-density multi-hole spacer which can reduce the material per the number of holes per unit pipe line and can enhance the strength more than laying a single pipe, and enables cables to be laid stably and easily, forming a small-diameter spacer within a tube. SOLUTION: This high-density multi-hole spacer includes a tube main body where a plurality of pipe lines are made inside in the axial direction of a pipe so as to store a plurality of cables different in diameter, a pipe coupling groove which is made long in the axial direction of the above tube main body outside the pipe main body, a binding hole which is made through from the wall face of the pipe coupling groove to the end face of the pipe main body, a coupling means which couples the adjacent pipe main bodies, being passed in the binding holes, and a shifting means which can shift the above pipe main body only in the pulling direction.
