Abstract (in Japanese) (See Japanese page) 
(in English) In magnetic resonance type radio electric power transmission, when a foreign substance approaches a coil, impedance mismatching occurs. Thereby, the transmission efficiency in frequency to perform electric power transmission in deteriorates. In this paper, the composition which uses the loop for a resonance coil and excitation is used. In order to improve degradation of the transmission efficiency of this system, the composition which adds a capacitor to the loop by the side of power transmission is used.Because the impedance matching is done by adjusting the capacity value of the capacitor to minimize the amount of the reflection from the power transmission side, and the thing that the transmitting efficiency in the frequency in which the electric power wants to transmit is improved was confirmed by the measurement, it reports.
