A power transmission coil unit includes a power transmission coil formed such that a lead wire is spirally wound around a coil axis extending in a first direction. Sensor modules each include a sensor having a detection range of a first angle that is a detection angle spanning in an in-plane direction of a first plane orthogonal to the first direction. The sensors are disposed in a surrounding region that is, as viewed in the first direction, a region surrounding the power transmission coil unit along an outer edge of the power transmission coil unit. The sensors are disposed such that a second angle or an angle between a straight line overlapping the detection range, among straight lines constituting the outer edge of the power transmission coil unit, and a center axis of the detection range is ½ or less of the first angle.
