Abstract
A contactless power transferring coil unit is provided. The contactless power transferring coil unit includes a flat coil, a magnetic film, and a leaking flux detecting coil. The flat coil is formed by winding a conductive wire into a spiral on a substantially flat plane. The magnetic film is disposed so as to cover one entire flat surface of the flat coil. The leaking flux detecting coil is disposed in a periphery outside an outer edge of the flat coil and the magnetic film and detects leaking magnetic flux from the flat coil.
