A charging port includes an inlet, a charging-in-progress lamp, and a communication-in-progress lamp. The inlet is configured to be connectable with a charging cable. During external charging by a charger, the charging-in-progress lamp indicates that external charging is being performed. Specifically, while the charging-in-progress lamp receives from a charging ECU a signal which indicates that external charging is being performed, the charging-in-progress lamp is lit. The communication-in-progress lamp is provided adjacently to the charging-in-progress lamp for indicating, while PLC-based communication by means of the charging cable is in progress, that PLC is being performed. Specifically, the communication-in-progress lamp is lit while the communication-in-progress lamp receives from the charging ECU a signal indicating that PLC is being performed.
