Abstract
In the present invention, junction capacitance is increased by stabilizing the junction capacitance of rotating electrodes such that a short circuit does not occur between the electrodes. Provided is a rotating electrode unit comprising a rotor electrode unit in which one or more rotor electrodes and one or more rotor spacers are alternately stacked, and a stator electrode unit in which one or more stator electrodes and one or more stator spacers are alternately stacked, wherein the rotating electrode unit is configured such that when the rotor electrodes are power transmitting electrodes, the stator electrodes are power receiving electrodes, when the rotor electrodes are power receiving electrodes, the stator electrodes are power transmitting electrodes, the rotor electrode unit and the stator electrode unit are combined in a nesting arrangement so as to be mutually rotatable, at least the outer peripheral section of the rotor electrodes is constituted by a member comprising a magnetic body, and the stator spacers have a magnet which attracts the outer peripheral section of the rotor electrodes via magnetic force.
