摘要：
The re-peelable pressure-sensitive adhesive sheet of the invention is a re-peelable pressure-sensitive adhesive sheet, which comprises an adhesive layer formed over a base film, and which further comprises at least one intermediate layer between the base film and the adhesive layer, the intermediate layer having a storage elastic modulus (G′) of 3.0×104 to 1.0×108 Pa at 23° C. and a storage elastic modulus (G′) of 1.0×103 to 8.0×104 Pa at 200° C.
