The utility model provides a matt-black single-sided adhesive tape with high shading. The matt-black single-sided adhesive tape comprises a release paper layer and a base material layer as well as an adhesive layer arranged between the release paper layer and the base material layer, wherein the outer surface of the base material layer is provided with a black high-shading coating layer. The matt-black single-sided adhesive tape provided by the utility model has the advantages that by the high-shading black coating layer on the outer surface of the base material layer, the appearance defects on the surface of a shielding material or a wave-absorbing material (such as ferrite) can be effectively covered and the shielding performance can not be influenced, so that the defects of the existing single-sided adhesive tape are overcome, and the application to novel handheld electronic equipment is achieved.
