Abstract
The present invention of an electrostatic coupling type contactless electric power supply devicehas multiple electrodes for contactless electric power supplyand a high-frequency power source circuitprovided on a fixed section, multiple electrodes for contactless electric power receptionand an electric power reception circuiton a movable section, wherein the electrode for contactless electric power supplyand the electrode for contactless electric power receptionhave base sectionswith a perpendicular cross sectional shape to the moving direction of the movable sectionand there are multiple extending tooth sections, and fellow tooth sectionsare mutually alternating and separated to fit together in an interdigitated array electrode, furthermore, the electrode for contactless electric power receptionis an interdigitated array electrode with the outer surface of the tooth sectioncovered with a conducting layerand the tooth sectioninternal section and the base sectionare formed from material that has a smaller specific gravity than the conducting layer. And from this, the electric power supply capacity and electric power supply efficiency of the contactless electric power supply is improved from that conventionally, and the movable sectionwhich is the power supply target can be lighter.
