<P>PROBLEM TO BE SOLVED: To obtain an induced-power transmission system transmitting power to a remote device at a large interval from a power device with a high transmission efficiency and being capable of transmitting a large power by low suppressing a voltage applied to electronic parts of a device subjected to power feeding in this case. Ž<P>SOLUTION: In the induced-power transmission system, a transmission antenna and a receiving antenna have capacities connecting both ends of coil-shaped wirings, a resonance circuit is composed of the capacities and the inductances of the coil-shaped wirings and coils for the transmission antenna and the receiving antenna are arranged at a distance of twice or less of the diameters of the coils for both antennas. In the induced-power transmission system, a power circuit and a load circuit are connected in series in the intermediate section of the coil-shaped wirings, the output impedance of the power circuit is matched with a resistor induced to the transmission antenna, and the input impedance of the load circuit is matched with the resistor induced to the receiving antenna, thus transmitting the power from the power circuit to the load circuit. Such an induced-power transmission system is manufactured. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
