WIRELESS POWER TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power-receiving resonator that maintains high transmission efficiency without wastefully increasing a total amount of wiring in a wireless power transmission system in which a size difference exists between power-transmission and power-receiving resonators.SOLUTION: A power-receiving resonator 107 includes a second inductor having a second size smaller than a first size of a first inductor included in a power-transmission resonator 105. A resistance value per unit length in at least one part of resonance frequencies of a wiring constituting the second inductor is set lower than a resistance value per unit length in resonant frequencies of a wiring constituting the first inductor.
