Abstract
Provided is a wireless power transmission device to reduce an electromagnetic wave except for a signal to be transmitted during wireless power transmission, the wireless power transmission device including a transmitter configured to generate a magnetic field by inputting a high-frequency power signal generated by a transmission circuit into a first coil, a receiver configured to generate an induced current by allowing the generated magnetic field to pass through a second coil, and a reducer configured to reduce a harmonic component of the high-frequency power signal using a third coil inserted on a path between the transmitter and the receiver.
