A charging device charges an in-vehicle battery for an electric vehicle by a power supply fed from an attachment plug extending from an external power supply. The charging device includes: a charging inlet; a housing recess formed within the charging inlet; a charging connector disposed within the housing recess; and an illumination light source embedded in an upper peripheral wall of the housing recess. The illumination light source emits light downward, and an optical axis thereof is positioned closer to an opening of the housing recess than a front surface of the charging connector. A first irradiation light emitted toward the opening of the housing recess than the optical axis is emitted obliquely downward from the charging inlet. A second irradiation light emitted toward a bottom of the housing recess than the optical axis is emitted to the charging connector.
