To provide a wireless charging system which is capable of suppressing reduction of an electric power feeding efficiency due to imperfect alignment even when the imperfect alignment is caused between a transmitter unit and a receiver unit. A wireless charging system includes a first coil portion 18 fixed to a first magnetic member 14, and a second coil portion 15 fixed to a second magnetic member 21. The first coil portion and the second coil portion are made close to each other to be disposed so as to face each other, thereby feeding electric power from one coil portion to the other coil portion. The wireless charging system further includes a convex portion 24 which is mounted to the first magnetic member so as to protrude toward the second magnetic member when the first coil portion and the second coil portion are coaxially disposed; a cover 27 which covers the second coil portion; and a concave portion 29 which is provided in the cover so as to face the convex portion when the first coil portion and the second coil portion are coaxially disposed. The convex portion contains as a material thereof a magnetic material. |
