[Object] There is a problem in that it is not possible to increase the number of coils connected in series and the amount of electric power that can be transmitted by a wireless power supply device cannot be increased.[Solution] A contactless power supply coil unit according to an aspect of the present invention includes a plurality of coils wound around a predetermined center axis and a holding member that holds the plurality of coils. The plurality of coils are disposed at intervals so as to overlap each other in a radial direction and form respective annular layers that are stacked in the radial direction. The coils forming the layers that are adjacent to each other are connected in series to each other. The intervals between the layers that are adjacent to each other increase as the intervals are located progressively toward a radial-direction outer side.
