<p>Provided is a pressure-sensitive adhesive sheet with excellent antistatic performance, re-separating performance, and adhesion. The pressure-sensitive adhesive sheet has an adhesive layer on at least one side of a substrate. The adhesive layer is made of, as a raw material monomer, at least 70-99.5 wt% of a (meth)acrylic acid alkylester and 0.5-10 wt% of a carboxylic group-containing unsaturated monomer and water-dispersible acrylic adhesive composition. At a peeling angle of 180°and a peeling speed of 30m/min, the peeling strength ratio (B/A) of a peeling strength to a high polarity adherent (A) the surface roughness of which is 250-450 um to a peeling strength to a low polarity adherent (B) the surface roughness of which is 250-450 um is 0.7-1.5. The adhesive ratio to the low polarity adherent is 99.0% or higher, and initial peeling voltage (absolute value) is 1.0 kV or less.</p> |
