PROBLEM TO BE SOLVED: To provide an energization rotation device that surely performs energization without increasing an electric resistance value even if the temperature of a conductive medium rises. SOLUTION: The energization rotation device is provided with a rotating member 11 that rotates together with a rotary shaft 4, a fixed member 12 to which the rotating member 11 is rotatably mounted, a liquid or powdered conductive medium G1 that is sealed in the gap between the rotating member 11 and the fixed member 12 so as to allow the part between the rotating member 11 and the fixed member 12 to be energizable. Since conductive antioxidizing films 20, 21 are respectively formed on a contact face of the rotating member 11 and a contact face of the fixed member 12 that respectively contact with the conductive medium G1, it is possible to prevent the contact faces from being oxidized even if the temperature of the conductive medium G1 rises due to rotation of the rotating member 11. Therefore, it is possible to surely perform energization without increasing an electric resistance value even if the temperature of the conductive medium G1 rises. COPYRIGHT: (C)2008,JPO&INPIT
