Abstract
An electric power transmission device as an aspect of the present invention includes a plurality of power transmitters configured to respectively generate magnetic fields. Phases of the respective magnetic fields are set such that the respective magnetic fields cancel out each other. The power transmitters sequentially shift frequencies of the respective magnetic fields to the same value at the same timing. A shift width of each of the frequencies for one-time shifting is limited by an upper limit value.
