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.
