An on-board power line communication system that performs power line communication during charging and discharging of a battery prevents electromagnetic wave leakage from a power line from interfering with other on-board devices. A vehicle includes a PLC communication device that performs PLC communication using a charging cable that is connected to a battery, and an interference suppressor that prevents electromagnetic wave leakage from the charging cable, which accompanies PLC communication, from interfering with the operations of an on-board electronic device. The interference suppressor reduces electromagnetic wave leakage from the charging cable by reducing the output frequency of the PLC communication device or the value of current flowing through the charging cable while the on-board electronic device is performing a specific operation that will be affected by interference from PLC communication.
