An induction coil structure for a wireless charger includes at least one first coil, at least one second coil, a first magnetic conductor and a second magnetic conductor. The first coil is disposed in a first layer of an induction coil. The second coil is disposed in a second layer of the induction coil. The first magnetic conductor is located between the first coil and the second coil, wherein a first surface and a second surface of the first magnetic conductor are superposed on the first coil and the second coil, respectively. The second magnetic conductor is superposed on a surface of the second coil that is not superposed on the first magnetic conductor. The first magnetic conductor includes a hole, and a wire for winding the first coil extends from the first layer to the second layer via the hole, to wind the second coil.
