PROBLEM TO BE SOLVED: To provide a power line communication system capable of maintaining a degree of balancing of communication wiring in a high state. SOLUTION: Power lines 4A and 4B connect a battery 2 and an electric device 3. Furthermore, a branching part 5 branches from the plus-side power line 4A to communication combined power lines 7A, 7B. The communication combined power lines 7A, 7B are connected to a communication section 9 of a communication device 8 and connected to a plus-side power supply terminal 10A via a connection part 11. Thus, differential signals are superimposed on the communication combined power lines 7A, 7B and communication can be performed among a plurality of communication devices 8. Furthermore, power from the battery 2 can be supplied to the communication device 8 using the communication combined power lines 7A, 7B. COPYRIGHT: (C)2011,JPO&INPIT
