Abstract
An electric power transmission system that includes a power receiving device having a first coupling electrode and a power transmission device having a second coupling electrode, both the devices being coupled via an electrostatic field, and the power transmission device configured to transmit electric power to the power receiving device in a noncontact state. The power transmission device includes a third coupling electrode that is disposed at a distance from the second coupling electrode. The third coupling electrode has a potential higher than that of the second passive electrode and lower than that of the second active electrode.
