According to the aramid paper with the high mechanical performance and the electromagnetic shielding performance, the electromagnetic shielding layer is bonded to the surface of the aramid paper, so that the aramid paper has the mechanical performance such as high tensile strength and the electromagnetic shielding performance such as low dielectric constant; meanwhile, the composition in the electromagnetic shielding layer is improved, an oriented carbon-based conductive material and a non-oriented magnetic material are compounded, and the non-oriented magnetic material is filled in a gap formed by intersection of the oriented carbon-based conductive material, so that the overall electromagnetic shielding performance of the electromagnetic shielding layer can be improved; therefore, the technical problem that an electromagnetic shielding material in the prior art does not have high mechanical performance and electromagnetic shielding performance at the same time is solved.
