The invention is concerned with the field transmitting equipment, including: the supporter, the electric conducting material, and at least one section of carbon nanometer pipeline, the electric conducting material fixes the carbon nanometer pipeline on the supporter. The invention provides the preparation method of the field transmitting equipment, which makes at least one section of carbon nanometer pipeline fix on the supporter using the electric conducting material by sticking and sinter way. The invention is not only simple and better operation, but also not easy to be drawn by bigger electric field effect.
