A wireless power-supplying system configured to perform wireless power supply using a power-receiving coil and a power-transmitting coil. The wireless power-supplying system includes a power-receiving circuit provided with the power-receiving coil having impedance changer configured to change impedance when requiring stopping the wireless power supply, and a power-transmitting circuit provided with the power-transmitting coil having impedance change detector configured to detect change in impedance by the impedance changer, and the wireless power supply is stopped based on a detection result of the impedance change detector.
