Disclosed is a highly conductive coating, which is composed of conductive microspheres and a polymer adhesive, wherein the volume ratio of the conductive microspheres to the polymer adhesive is 1:2 to 2:1, and the conductive microsphere is a conductive microsphere plated with silver or copper. The highly conductive coating can has a density that is as close as possible to that of a carbon fiber reinforced composite material, without adding extra weight to the composite material product. In addition, the coating has a surface resistivity as low as 0.01 Ω/square, such that the conductivity is not less than that of a conductive coating of a copper powder filler. Lightning strikes can be prevented and the interference of static electricity on electromagnetic waves can be eliminated. The highly conductive coating can be used in a surface coating of a composite material of a plane, a high-speed train, an unmanned aerial vehicle, a wind turbine blade or a car made of the composite material, and effectively solves the problem that existing commercial conductive coatings are not very suitable for such product coatings.
