An aim of the present invention is to provide a pressure-sensitive adhesive sheet excellent in antistatic property, re-peelable property, and adherability (tackiness). A pressure-sensitive adhesive sheet according to the present invention includes a substrate and a pressure-sensitive adhesive layer on at least one surface of the substrate, wherein the pressure-sensitive adhesive layer is formed of a water dispersion type acryl-based pressure-sensitive adhesive composition containing an acrylic emulsion-based polymer containing at least 70 to 99.5% by weight of a (meth)acrylic acid alkyl ester (A) and 0.5 to 10% by weight of a carboxyl-containing unsaturated monomer (B) as raw material monomers and an ionic compound; a peeling power ratio ((B)/(A)) of a peeling power (B) for an adherend surface with a surface roughness Ra of 250 to 450 μm and low polarity to a peeling power (A) for an adherend surface with a surface roughness Ra of 5 to 50 μm and high polarity measured at a peeling speed of 30 m/minute and a peeling angle of 180° is 0.7 to 1.5; the adhesion to the low polarity adherend surface is 99.0% or higher; and an initial peeling electrification voltage (absolute value) is 1.0 kV or lower.
