Wireless power transfer technologies have been developing in various fields. One method of the wireless power transfer is one using electric field coupling. Capacitors are used in the method. If transparent conductive film as the electrodes are used, electric power can be transfer through a windowglass. In this report, as an initial study for a wireless power feeding through a window glass, the electric characteristics of capacitors using a transparent conductive film were investigated. At first, the capacitances and the electric losses were measured. Next, a new capacitor structure was proposed in order to reduce the electric losses. The transparent conductive film was divided and connected in parallel. The total loss resistance was reduced from 22. 4 Ω to 5. 30 Ω by using the structure. The transmission efficiencies were measured of 53.7% for the load resistance was 9. 74 Ω, 85.9% for 45. 9 Ω, and 97.1% for 97. 9 Ω.
