With the development of high-speed switching devices, research on wireless power transfer system using megahertz bands has been increasing. The size and weight of the coupler can be reduced using megahertz bands. However, the loss of the coupler owing to the skin effect and the proximity effect must be considered in the high frequency range. Therefore, in this paper, a two-layer open spiral coupler using copper foil for the coil is proposed. Moreover, it is experimentally confirmed that the proposed two-layer open spiral coupler using copper foil achieved high-efficiency high-power transmission using high frequency 13.56MHz at a transmission distance of 300mm.本誌: 電気学会論文誌D（産業応用部門誌） Vol.143 No.7 （2023）本誌掲載ページ: 547-552 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/143/7/143_547/_article/-char/ja/
