According to an embodiment of the present invention, a wireless power transfer unit comprises: a resonant coil unit; an inductive coil unit; and a loss suppressing unit including a serial resonant circuit connected to both ends of the inductive coil unit, wherein the loss suppressing unit resonates at a first frequency to drive the resonant coil unit. Therefore, the wireless power transfer unit can minimize an influence on a magnetic induction operation. |
