Abstract
A power transmission device that includes a high-frequency high-voltage generating circuit which applies a high voltage of high frequency between a power transmission device side active electrode and a power transmission device side passive electrode, the power transmission device side passive electrode being disposed in a manner to surround the power transmission device side active electrode and the high-frequency high-voltage generating circuit. An auxiliary high-frequency high-voltage generating circuit is provided between a ground of the power transmission device having a potential substantially equal to the ground potential and the power transmission device side passive electrode. The auxiliary high-frequency high-voltage generating circuit suppresses a potential change of the power reception device side passive electrode relative to the ground potential.
