UNIT CABLE AND USE THEREOF

PROBLEM TO BE SOLVED: To provide a unit cable which can reduce attenuation of communication signals due to reflection and is suitable for a signal transmission line for power line carrier communication, and use thereof. SOLUTION: Interior wiring of a house 100 comprises the unit cable 1. The cable 1 has a plurality of branch wires 10a to 10f and a branch connection part 11 connecting one-end sides of those branch wires 10a to 10f. The branch wires 10b to 10f other than the branch wire 10a which is connected to a power distribution board 51 to serve a power line are all equal in length. When power line carrier communication is carried out by using interior wiring comprising such a cable 1 as a signal transmission line for the power line carrier communication, attenuation of communication signals due to reflection is reducible.
