PURPOSE: A wireless power transmitting device and system are provided to guarantee transmission efficiency by arranging two transmission coil parts for wireless power electrical transmission. CONSTITUTION: A first transmission coil part(131) wirelessly transmits electricity provided from a power source to a receiving coil part. A first electricity coil is electrically connected to the power source and receives electricity from a power source. A first transmission resonator is magnetically connected to the first electricity coil. A second transmission coil part(132) is separately placed with the first transmission coil part and comprises a second transmission resonator. The first transmission resonator and the second transmission resonator transmit electricity to the receiving coil part by resonance of the receiving coil part. |
