Provided is a wireless power supply system that can simultaneously supply power wirelessly to a plurality of appliances as well as to different appliances. A plurality of primary coils (L1) are disposed on the same surface and a power supply module (M) is provided for each primary coil (L1). Additionally, when each power supply module (M) transmits an appliance authentication signal (ID) and an excitation request signal (RQ), a system control unit (8) transmits a permission signal (EN), which permits the continuous excitation of the primary coil (L1), to the power supply module (M). A plurality of appliances (E) mounted on the mounting surface can be simultaneously supplied with power by the continuous excitation of only the primary coils (L1) directly underneath appliances (E) when the appliances (E) are mounted on the mounting surface. |
