PURPOSE: A wireless power transmission device is provided to maximize transmission and reception efficiency using a structure of the wireless power transmission device and to implement miniaturization. CONSTITUTION: A wireless power transmission device (230) comprises a first coil, a second coil, and a third coil (233) capable of being connected with one conducting wire. The first coil comprises a first outline (231a), a second outline (231b), a third outline (231c), and a fourth outline (231d). The outlines of 4 are connected and form a rectangular shape. A transmission induction coil and a transmission resonance coil are prepared if electricity is transmitted with self resonance. The transmission induction coil is prepared only if electricity is transmitted with electromagnetic induction. [Reference numerals] (100) Electricity source |
