1. A wireless power transmission resonator comprising:
a first element comprising a first element upper part arranged in an upper end of a resonator and a first element lower part arranged in a lower end of the resonator, wherein the first element upper part comprises a spiral layer having a spiral structure that is wound to face a wide surface of a conducting wire comprising a vertical rectangular cross-section and the first element lower part comprises a spiral layer having a spiral structure that is wound to face the wide surface of the conducting wire comprising the vertical rectangular cross-section;
a second element arranged in a center of the resonator and between the first element upper part and the first element lower part and comprising a spiral layer having a spiral structure that is wound to face the wide surface of the conducting wire comprising the vertical rectangular cross-section; and
a power supply connected to the first element or the second element and configured to provide power to the resonator.
