The present invention relates to a wireless power transmission device using a relay device. The present invention provides the wireless power transmission device using the relay device comprising a transmitter including a primary transmission coil which is connected with a socket so that a power supply is executed. The primary transmission coil receives a current flowing in the socket and transmits power. The wireless power transmission device using the relay device comprises a relay including a reception coil for a relay which receives the power transmitted from the transmitter and forms resonance with the transmitter by a ceramic resonance phenomenon and wirelessly receives the power transmitted from the transmitter at a long distance. The relay rectifies and transfers the power. The wireless power transmission device using the relay device comprises a portable device which receives the power transmitted from the relay and charges a battery. According to the present invention, the wireless power transmission device is miniaturized and a wireless power transmission distance is extended by increasing a transmission distance of the wireless power transmission device and miniaturizing the size of a receiver. |
