Summary: | 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
