RESONANT ELECTRICAL POWER TRANSMISSION DEVICE AND RESONANT ELECTRICAL POWER MULTIPLEXED TRANSMISSION SYSTEM

Disclosed is a resonance type power transmission device that transmits electric power by using a resonator for transmission 3 and a resonator for reception 4 whose resonance conditions are matched to each other, the resonance type power transmission device including a transmission power supply 1 to supply electric power, a transmission antenna 2 to transmit the electric power from the transmission power supply 1, a conductive substance 7 to establish an electrical single point connection between the resonator for transmission 3 and the resonator for reception 4, a reception antenna 5 to receive the electric power from the transmission antenna 2 via the resonator for transmission 3 and the resonator for reception 4, and a reception power supply 6 to receive the electric power received by the reception antenna 5.
