PROBLEM TO BE SOLVED: To provide a compact device performing energy transmission and data transmission, in non-contact, between two objects rotating relatively around the axis of rotation, and strong to noise.SOLUTION: A device includes circular or arcuate first and second coils 14, 114 facing each other in the axial direction of the axis of rotation A, and performing energy transmission by induction coupling, and circular or arcuate first and second conductors 12, 112 provided coaxially with the first and second coils 14, 114, and facing each other while separated in the axial direction, and performing data transmission by electrical coupling. The carriers of the first coil 14 and first conductor 12 and of the second coil 114 and second conductor 112 are constituted, respectively, as integral wiring boards 10, 110. Between the first coil 14 and conductor 12 and/or between the second coil 114 and conductor 112, placement products 18, 118 composed of a conductive material are installed, and through holes 20, 120 formed in the wiring boards 10, 110 are filled with a conductive material.SELECTED DRAWING: Figure 1 【課題】回転軸を中心として互いに相対的に回転する２つの物体の間で、エネルギー伝送とデータ伝送を非接触で、ノイズに強く、コンパクトに行う装置を提供する。【解決手段】回転軸Ａの軸方向に離間して対向し、誘導結合によるエネルギー伝送を行う円状又は円弧状の第１、第２コイル１４、１１４と、第１、第２コイル１４、１１４と同軸に設けられ、軸方向に離間して対向し、電気的な結合によるデータ伝送を行う円状又は円弧状の第１、第２導電体１２、１１２を備える。第１コイル１４と第１導電体１２及び第２コイル１１４と第２導電体１１２の担持体は、それぞれ一体的に配線基板１０、１１０として構成される。第１のコイル１４と導電体１２の間及び／又は第２のコイル１１４と導電体１１２の間には、導電性材料から成る遮蔽用の配置物１８、１１８が設置され、さらに配線基板１０、１１０に形成された貫通穴２０、１２０に導電性材料が充填される。【選択図】図１
