Abstract (in Japanese) (See Japanese page) 
(in English) It is necessary to elucidate the influence of the salt water to a resonator in order to improve the efficiency of the WPT system under seawater. We have chosen in a spiral resonator which has the highest space efficiency in resonators and measured its unloaded Q resonant frequency, salinity, the magnetic / electric coupling ratio. The seawater is an electrolyte including electrolytes such as NaCl and thus, we want to catch a clue for elucidating the resonator loss mechanism by such electrolyte as the seawater based on these data. In addition, we have tried to calculator the electromagnetic field energy to find the key to new elucidation of the loss mechanism in this report.
