Abstract: A power transmission device includes a first coil and a second coil. The first coil emits a first electromagnetic wave. The second coil is arranged at a position where a center axis of the first coil and a center axis of the second coil are not overlapped to each other and emits a second electromagnetic wave having a strength distribution with a polarity opposite to a polarity of a strength distribution of the first electromagnetic wave.
