ELECTRIC POWER TRANSMISSION PATH

摘要

PROBLEM TO BE SOLVED: To provide a method of constructing an electric power transmission path which supplies power to a long-interval electric power transmission path by a single high-frequency power source and can reduce variation of electric characteristics depending on the position of a movable body on the transmission path.SOLUTION: An electric power transmission path includes a contact region with which a movable body comes in direct or indirect contact to supply high-frequency power, electrode regions which are formed by dividing the contact region into a plurality of sub-regions and composed of a conductive material, and a high-frequency power source which supplies high-frequency power to the electric region. A plurality of electrode pairs are formed by combining two or more of the electric regions as one set, and the electrode pairs are connected mutually between adjacent electrode pairs or to the high-frequency power source.
