A wireless power transmission system for use in an elevator system includes a power transmitting electrode unit including at least two power transmitting electrodes, and a power receiving electrode unit arranged on a carriage and including at least two power receiving electrodes for receiving electric power output from the at least two power transmitting electrodes. The power transmitting electrode unit is arranged so as to oppose at least a portion of the power receiving electrode unit when the carriage is at rest at a predetermined power-supplying floor and is extended in at least one of an upward direction and a downward direction. Electric power is transmitted from the power transmitting electrode unit to the power receiving electrode unit when the carriage is at rest at the power-supplying floor, when the carriage is accelerating off the power-supplying floor, and/or when the carriage is decelerating toward the power-supplying floor.
