Claim Text:
1. A power transfer system comprising: a power transmission device having a power transmission capacitive coupling electrode that includes a power transmission central conductor and a power transmission peripheral conductor that is arranged at a position surrounding the power transmission central conductor or at positions placing the power transmission central conductor in between in an insulated state from the power transmission central conductor; a power reception device having a power reception capacitive coupling electrode that includes a power reception central conductor and a power reception peripheral conductor that is arranged at a position surrounding the power reception central conductor or at positions placing the power reception central conductor in between in an insulated state from the power reception central conductor; an alternating voltage generating circuit that generates an alternating voltage that is applied between the power transmission central conductor and the power transmission peripheral conductor; and a load circuit of electric power induced between the power reception central conductor and the power reception peripheral conductor, wherein the power transmission central conductor operates as a high-voltage side electrode while the power reception peripheral conductor operates as a low-voltage side electrode.
