NOVELTY - The device (500) has a power receiving part comprising a charging connector (250) and closed by a lid. A lid opening and closing switch (520) is connected in series with a lighting unit (206). The power receiving part is set to conduction state and non-conduction state respectively when the lid is closed and opened. A switch e.g. solid state relay (SSR) (510) or photocoupler, is connected in series with the lighting unit, and a power supply node (420) is set to non-conduction state and conduction state respectively when the connector is connected to and removed from the power receiving part.    USE - Illuminating device for a vehicle e.g. electric vehicle such as fuel cell electric vehicle, and hybrid vehicle.    ADVANTAGE - The solid state relay (SSR) is set to the conduction state when the charging connector is not connected to the power receiving part, so that electric current flowing from the power supply node lights the lighting unit, thus enabling a user to confirm the position of the power receiving part. The SSR is set to the conduction state when the connector is removed from the power receiving part, so that lighting unit is extinguished, thus checking whether the charging connector is suitably connected to the power receiving part. The unnecessary lighting of the lighting unit is suppressed while externally charging the electrical storage apparatus using the charging device, thus reducing power consumption of the device. The device solves the problem of security while avoiding notification of surroundings of the vehicle about charging operation. The lighting unit is illuminated when the lid is closed, thus reminding the user to close the lid. The lighting unit is illuminated and light-extinguished according to connection or removal of the charging connector with the power receiving part, thus suppressing increase in number of parts by providing the light emission part for detecting connection state of the charging connector, and hence suppressing increase in number of parts of the device and simplifying the structure of the device.
