The normal-temperature Pi electron high conductor comprises two flat normal-temperature Pi electron high conduction elements which are identical in structure and are stacked. The flat normal-temperature Pi electron high-conductivity element is formed by stacking a flat conductive excitation body and a Pi electron plane excitation network; the flat conductive excitation body adopts a flat conductor; the Pi electron plane excitation network is of a net structure which takes an insulating resin adhesive as a continuous phase and takes a material with Pi electron elements as a dispersed phase, and Pi electrons are arranged in order under the constraint of Lorentz force and Coulomb force in a standard field of the Pi electrons and are cured on the flat conductive excitation body. The invention further discloses a preparation method of the normal-temperature pi electron high conductor in the zero magnetic vector field. The high conductor provided by the invention is high in normal-temperature conductivity, can be used for preparing a power-on bar, a motor winding and a transformer winding for low-voltage power distribution below 35000V, can replace copper with aluminum to save copper, realizes cost reduction and efficiency improvement, and is wide in market prospect and huge in economic value.
