A method for laying a cable using a conduit comprising a suspension wire, one or more hangers held by the suspension wire and having an accommodation space that accommodates the cable, and a groove extending along an axial direction of the suspension wire, wherein the groove has an opening connected to the accommodation space and the opening has a width smaller than a maximum width of an interior of the groove, the method comprising:
- connecting the cable to a first end on a thin-wire portion side in a wire-carrying member having a thin-wire portion and a thick-wire portion thicker than the thin-wire portion;
- inserting the wire-carrying member into the groove from a second end on a thick-wire portion side in the wire-carrying member;
- and
- inserting the cable into the accommodation space by pulling the cable through the wire-carrying member while holding the thick-wire portion in the groove and positioning the thin-wire portion in the accommodation space, wherein
- the thin-wire portion is thinner than the width of the opening, and
- the thick-wire portion is thicker than the width of the opening and thinner than the maximum width of the interior of the groove.
