Beschreibung
Zusammenfassung:	The present invention provides an optical-use pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer having, as measured through dynamic viscoelastometry, a storage elastic modulus at 80° C. of at least 2.0×104 Pa and a loss elastic modulus at 80° C. of at least 1.0×104 Pa, in which the pressure-sensitive adhesive sheet has a peel force, as measured in the L-shape peel test, of at least 0.16 MPa, and has a peel distance, as measured in the constant-load peel test (under a load of 100 gf for 3 hours), of at most 50 mm.
