PROBLEM TO BE SOLVED : To provide a re-releasable adhesive sheet, which can be peeled even after a long time period after the sheet has been bonded to a glass surface such as a flat panel display and enables reuse (rework) of members.
SOLUTION : An adhesive layer is formed on one surface of a transparent substrate, wherein the adhesive layer comprises an acrylic polymer containing an acrylate as a principal component and having a weight-average molecular weight ranging from 700, 000 to 1, 500, 000, which can be obtained by copolymerization of the acrylate and a copolymerizable hydroxy group-containing monomer or carboxyl group-containing monomer, and an adhesive composition containing a crosslinking agent.
