A power line communication system in which a home\'s power line communication unit can communicate with a vehicle even when a relay is broken off without using a special relay. In this system, a vehicle\'s PLC communication unit ( 21 ) mounted in a vehicle ( 2 ) and a home\'s PLC communication unit ( 42 ) installed in a home communicate via a power transmission unit ( 3 ) that transmits communication signals and power to be supplied to the vehicle ( 2 ). The power transmission unit ( 3 ) includes a mechanical relay for conducting or shutting off power to the vehicle ( 2 ). The home\'s PLC communication unit ( 42 ) transmits a communication request signal for starting communication to the power transmission unit ( 3 ). When the vehicle\'s PLC communication unit ( 21 ) receives the communication request signal transmitted by the home\'s PLC communication unit ( 42 ), the vehicle\'s PLC communication unit ( 21 ) energizes the mechanical relay and then starts communication.
