A displacement of a foreign object is detected on the basis of a position of the foreign object at each of a starting time and a finishing time of a predetermined period. By delaying the timing for determining the displacement mode of the foreign object by the predetermined period (predetermined time), the timing for providing notification recommending the removal of the foreign object can be delayed. When after it is determined that displacement of the foreign object present around a power transmitting unit is present, the presence of the foreign object is not detected, that is, in a state where it is not necessary to provide the notification recommending that a user remove the foreign object, that notification is omitted.
