Abstract:
To provide a double-sided adhesive tape having reworkability.SOLUTION: There is provided a double-sided adhesive tape 1 which comprises a release sheet 10 and an adhesive layer 20 laminated on one surface of the release sheet 10, wherein the adhesive layer 20 has a plurality of concave shapes 20a on both surfaces of the adhesive layer. Since the concave shapes 20a function as a suction cup to exhibit adsorption action, the adhesive force to an adherend is generated and since the adsorption force itself of each of the concave shapes 20a is small, peeling can be easily performed and the adhesive force is not reduced even if re-applied and a double-sided adhesive tape having reworkability can be formed.SELECTED DRAWING: Figure 2
