PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet which is prepared by applying an aqueous-dispersion-type pressure-sensitive adhesive obtained by the copolymerization of a monomer mixture containing an alkyl (meth) acrylate, as the main component, and a silane monomer to at least one side of a substrate to form thereon a pressure-sensitive adhesive layer and which hardly increases the force to peel from a release liner coated with a silicone release agent or from a backside treatment layer. SOLUTION: This acrylic pressure-sensitive adhesive sheet is prepared by applying an aqueous-dispersion-type acrylic pressure-sensitive adhesive composition comprising a copolymer obtained by the copolymerization of the monomer mixture containing the alkyl (meth)acrylate, as the main component, and a silane monomer to at least one side of the substrate to form thereon the pressure-sensitive adhesive layer, provided the content of ammonia remaining in the pressure-sensitive adhesive layer is not higher than 400μg per g of the pressure-sensitive adhesive.
