PROBLEM TO BE SOLVED: To provide a cable-less power supply apparatus that does not require a power source, a charging device, or a charging cable, that improves flexibility in installation, and that is capable of supplying electric power even in a power failure. SOLUTION: This cable-less power supply apparatus consists of an antenna 1, a tuning circuit 2 that is tuned to a particular frequency with the antenna 1, a rectifier circuit 3 that converts an AC transmitted via the antenna 1 and the tuning circuit 2 into an DC, and an electric double layer capacitor 4 that stores the electric energy converted into the DC by the rectifier circuit 3. The electric power stored in the capacitor 4 from the antenna 1 via the tuning circuit 2 and the rectifier circuit 3 is supplied to a load device 5. COPYRIGHT: (C)2004,JPO&NCIPI
