PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet to prevent tunneling and warpage of an adherend. SOLUTION: This pressure sensitive adhesive sheet 10 is constructed by laminating a pressure-sensitive adhesive layer 12 and a release sheet 13 on a substrate sheet 11 in this order. The release sheet 13 is constructed by laminating a release agent layer 14 to be adhered to the pressure-sensitive adhesive layer 12 and a substrate 15 supporting the release sheet 13, from the side of the pressure-sensitive adhesive layer 12. The release agent layer 14 is constructed by permitting the release agent to contain a swellable particulate. Peeling force of the release agent layer 14 against the pressure-sensitive adhesive layer 12 is reduced when an external stimulation is imparted to the pressure-sensitive adhesive layer.
