A pressure-sensitive adhesive sheet contains at least a pressure-sensitive adhesive layer containing an acrylic pressure-sensitive adhesive containing an acrylic polymer composition containing an acrylic polymer as a main component and a tackifier containing a tackifying resin as a main component, wherein reflection rate and attached amount in the fogging test in accordance with German Industrial Standard DIN 75201 are 70% or more and 2.0 mg or less, respectively. In the acrylic pressure-sensitive adhesive which forms the pressure-sensitive adhesive layer, a ratio of components having a molecular weight of 300 or less is preferably 4.2% by weight or less based on the total amount of solid matter of the acrylic pressure-sensitive adhesive. Furthermore, in the tackifying resin in the tackifier, a ratio of components having a molecular weight of 300 or less is suitably 4.2% by weight or less based on the total amount of solid matter of the tackifying resin.
