Light applied from an illumination unit illuminates a space formed of an accommodation unit, and facilitates a user's operation of coupling a charging connector to an electric power-receiving unit. When a lid unit is in a closed state, a part of the light applied from the illumination unit toward the accommodation unit transmits through a light transmission member provided at the lid unit and leaks toward a space outside a vehicle body. The leaked light enables a user to visually perceive the position of the charging port at a glance even if the lid unit is in the closed state.
