Summary: | Provided is an active energy ray-peelable pressure-sensitive adhesive sheet which can be suitably used in a process under high-temperature conditions, and which can be easily peelable without leaving an adhesive residue on an adherend by sufficiently reducing the adhesiveness of a pressure-sensitive adhesive layer when irradiated with an active energy ray after use in the process. The pressure-sensitive adhesive sheet has a pressure-sensitive adhesive layer whose adhesive force is reduced by irradiation with active energy rays. The adhesive layer is composed of an active energy ray-curable adhesive. The active energy ray-curable adhesive is formed from a thermally cured product of an adhesive composition, and contains thermal reactants of (A) and (C). The adhesive composition contains at least (A) an adhesive base polymer having a hydroxyl group, (B) an active energy ray-reactive monomer having three or more radical-reactive groups in one molecule, (C) a cross-linking agent, and (D) an alpha-hydroxyalkylbenzo |
