Abstract
A coil unit for a contactless power supply system includes a plurality of coils for electric power transfer, and a magnetic flux reduction structure. The plurality of coils include a first coil and a second coil adjacent to the first coil in a predetermined direction. The magnetic flux reduction structure reduces, during electric power transfer using the first coil, magnetic flux by which the first coil causes an induced voltage or induced current to be generated in the second coil.
