The floor cable comprises a plurality of insulated core wires within a plastic cable sheath.Each of the insulated core wires has a plurality of folded portions along the wire length, and the cable sheath for the core wires has such cross section that a plurality of radial fins are provided on the thin circumference. Thus, the ripping out of the sheath for drawing out the desired wire to connect or branch the floor cable can be easily carried out.
