Abstract
A wireless power transfer system is configured in such a way that: the power transmitter coil and the power receiver coil each include a coil unit, the coil unit being a pair of coils arranged side by side in a horizontal direction; each of the coils in the coil unit has a shape formed by being wound in a horizontal plane and those coils are configured in such a way that magnetic fields generated by currents are oriented oppositely to each other; a connecting portion is provided on outside diameter sides of adjacent longer sides of the pair of coils, the longer sides being opposed to each other; and the coils are wound to be substantially point-symmetric about a substantially central point of the connecting portion as a point of symmetry in such a way that coil widths of all longer sides of the pair of coils are substantially equal.
