A charging stand is a power supply facility that is storable under a ground, and includes: a power supply unit (including a connector, a power supply cable and a power supply circuit) for supplying electric power to a vehicle on the ground; and a control device that controls supply of the electric power by the power supply unit. The control device allows the supply of the electric power by the power supply unit when the water is not accumulated inside the charging stand. With the above, when the water is not accumulated inside the charging stand, the power supply unit can supply the electric power to the vehicle.
