The purpose of the present invention is to provide a wireless power-supply system using magnetic resonance, which is different from the conventional point of view. In a wireless power-supply system (101), the positional relationship (distance C) between a power-supply resonator (102) and a power-receiving resonator (103) denotes the power-supply range (F). In the power-supply range (F), the electric power transmitted as magnetic energy by resonating the power supply resonator (102) and the power receiving resonator (103) is more than the predetermined effective power. Therefore, the predetermined effective power can be transmitted only in the power-supply range (F) that maintains the positional relationship. On the other hand, when the power-receiving resonator (103) deviates from the power-supply range (F), the electric power cannot be transmitted. |
