According to the present invention, there is provided a wireless charger including a resonator, which includes a transmitter for transmitting wireless power energy and a receiver for receiving wireless power energy, wherein a loop coil for transmitting and receiving wireless power energy is provided in the transmitter and the receiver, the coil is coupled to a condenser in series or in parallel, a resonator is further provided only in one of the transmitter and the receiver, and a relationship of RL X 0.8 <= CL <= 1.2 is satisfied when a length of a coil of the transmitter is CL and a size of a relay coil of the transmitter is RL. The resonator is provided only in one of the transmitter and the receiver, and accordingly, electric power and currents of the receiver is detected and controlled to maximize an efficiency of the wireless charger and an antenna loop coil may be located close to a case cover. |
