PURPOSE: A magnetic resonant wireless power transmission device is provided to improve wireless power transmission and local area network in a magnetic resonance method by attaching a magnetic resonant coil of a sticker form to a mobile device. CONSTITUTION: The magnetic resonant wireless power transmission device is composed of a source coil(200) for a local area network or wireless power electrical transmission, a device coil(300) located on a USIM(Universal Subscriber Identity Module) card(11) or a battery(12), and a rectifier circuit apparatus changing an AC voltage into a DC voltage. A first resonant coil(210) is located between a source coil and an external mobile device. A second resonant coil(310) is located between an internal device coil and an outer first resonant coil of the mobile device. The first resonant coil and the second resonant coil are respectively formed between the source coil and the device coil formed inside the mobile device.
