PURPOSE:To decrease the vibration by a supporting layer made of a synthetic resin and improve the rigidity by a supporting layer made of a metal, by providing the supporting layer made of the metal and the supporting layer made of the synthetic resin onto a conduit. CONSTITUTION:A conduit for a control cable is composed of the first conduit portion and the second conduit portion. The first conduit portion A1 is composed of a liner 1 made of the synthetic resin, and a supporting layer 3 formed with a strand of plural metal element wires 2 wound at a loose spiral angle, and a covering layer 4 made of such synthetic resin as polypropylene, etc., provided around the supporting layer 3. The second conduit portion B1 is composed of a supporting layer 5 formed with a pipe made of a polyacetal. Therefore, the vibration can be absorbed by the second conduit portion, moreover, the rigidity can be improved by the first conduit portion.
