To provide a wireless power transmission device which can suppress a temperature rise inside a unit having a coil for use for wireless power transmission.SOLUTION: A wireless power transmission device includes a coil unit which is exposed outdoors and performs wireless power transmission, and a control unit which controls the power transmission. The coil unit includes a coil, an electric component, a temperature detector unit, and a housing which accommodates the coil, the electric component and the temperature detector unit. The control unit includes a circulation system which circulates air, and a circulation control unit which controls the circulation system. When a temperature detected by the temperature detector unit exceeds a predetermined threshold, the circulation control unit causes the circulation system to make an air flow, having a low temperature below the threshold, to the inside of the housing of the coil unit.SELECTED DRAWING: Figure 1 【課題】ワイヤレスの電力伝送に使用されるコイルを備えるユニットの内部の温度の上昇を抑制することができるワイヤレス電力伝送装置を提供する。【解決手段】屋外に露出されてワイヤレスで電力伝送を行うコイルユニットと、前記電力伝送を制御する制御ユニットと、を備え、前記コイルユニットは、コイルと、電気部品と、温度検出部と、前記コイルと前記電気部品と前記温度検出部を収容する筐体と、を備え、前記制御ユニットは、空気を循環させる循環装置と、前記循環装置を制御する循環制御部と、を備え、前記循環制御部は、前記温度検出部により検出された温度が所定の閾値を超えた場合に、当該閾値以下の低い温度を有する前記空気を前記循環装置により前記コイルユニットの前記筐体の内部に流入させる、ワイヤレス電力伝送装置。【選択図】図１
