Optical-use pressure-sensitive adhesive sheet

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 × 10 4 Pa and a loss elastic modulus at 80°C of at least 1.0 × 10 4 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. Preferably the acrylic pressure-sensitive adhesive layer contains an acrylic polymer formed of one or more monomer ingredients including, as an indispensable monomer ingredient, an alkyl (meth)acrylate having a linear or branched alkyl group having from 1 to 14 carbon atoms and/or an alkoxyalkyl (meth)acrylate.
