Zusammenfassung:	The utility model discloses a directionally separated double-sided adhesive tape. The double-sided adhesive tape comprises a base material layer, a first adhesive layer, a second adhesive layer, a first release paper layer and a second release paper layer, wherein the first adhesive layer is arranged on one surface of the base material layer; the second adhesive layer is arranged on the other surface of the base material layer; the first release paper layer covers the first adhesive layer; the second release paper layer covers the second adhesive layer; the first adhesive layer is thicker than the second adhesive layer; or the first adhesive layer is a butyl acrylate pressure-sensitive adhesive layer, and the second adhesive layer is an ethyl acrylate pressure-sensitive adhesive layer. By using the structure that the first adhesive layer of the double-sided adhesive tape is thicker than the second adhesive layer or the first adhesive layer of the double-sided adhesive tape is the butyl acrylate pressure-sensi
