To provide a wireless power supply system, a power transmission device, and a power reception device that can improve the usefulness of wireless power supply technology that supplies power wirelessly to a mobile body.SOLUTION: A wireless power transmission system 1 includes a power transmission device 2 and a power reception device 3. The power transmission device 2 is installed on a road 4, includes a power transmission coil 21 that transmits electric power wirelessly, and is configured so that, when installed on the road 4, at least a part of the power transmission coil 21 is located vertically above a road surface of the road 4 in a width direction cross-section of the road 4, and a coil surface of the power transmission coil 21 is perpendicular to the road surface. The power reception device 3 includes a power reception coil 31 that is installed on a mobile body 5 and receives power wirelessly and is configured so that a coil surface of the power reception coil 31 is perpendicular to a contact surface of a wheel 6 of the mobile body 5 with the road surface in a cross-section in a width direction of the mobile body 5.SELECTED DRAWING: Figure 1

    【課題】移動体に対して無線で電力を供給する無線給電技術の有用性を向上させることができる、無線給電システム、送電装置、及び受電装置を提供する。【解決手段】無線給電システム1は、送電装置2と、受電装置3とを含む。送電装置2は、道路4に設置された送電装置2であって、無線により電力を送電する送電コイル21を備え、道路4に設置された状態で、道路4の幅方向断面において、送電コイル21の少なくとも一部が、道路4の路面よりも、路面に対して垂直方向上側に位置し、且つ送電コイル21のコイル面が路面と略垂直となるように構成されている。受電装置3は、移動体5に設置された受電装置3であって、無線により電力を受電する受電コイル31を備え、移動体5の幅方向断面において、受電コイル31のコイル面が、移動体5の車輪6の路面との接地面と略垂直となるように構成されている。【選択図】図1
