To provide a transmission device and an electric power transmission system for reducing detection dead angles in the vicinity of a power transmission coil in object detection associated with wireless power transmission.SOLUTION: A power transmission coil unit 210 has a power transmission coil configured by winding a conductive wire around a coil axis extending in a first direction. Each of a plurality of sensor modules 110 has a sensor having a detection range 115 where a detection angle extending in an in-pulse direction of a first surface orthogonal to the first direction is a first angle. A plurality of sensors is arranged in a surrounding area 215, which is an area surrounding the power transmission coil unit 210 along the outer edge of the power transmission coil unit 210 when viewed from the first direction. Each of the sensors is arranged such that a second angle formed by a straight line overlapping the detection range 115 among a plurality of straight lines 216 forming the outer edge of the power transmission coil unit 210 and a central axis of the detection range 115, when viewed from the first direction, becomes less than or equal to half the first angle.SELECTED DRAWING: Figure 6
【課題】ワイヤレス電力伝送に伴う物体検出において、送電コイルの周辺近傍における検出死角を低減する。【解決手段】送電コイルユニット210は、第1方向に沿って延在するコイル軸の周りに導線が巻回されて構成される送電コイルを有する。複数のセンサモジュール110は、第1方向と直交する第1面の面内方向に広がる検出角度が第1角度の検出範囲115を有するセンサをそれぞれ有する。複数のセンサは、第1方向から見て送電コイルユニット210の外縁に沿って送電コイルユニット210を囲む領域である包囲領域215に配置される。複数のセンサのそれぞれは、第1方向から見て、送電コイルユニット210の外縁を構成する複数の直線216のうち検出範囲115と重なる直線と検出範囲115の中心軸とのなす角度である第2角度が、第1角度の2分の1以下となるように配置される。【選択図】図6
