Disclosed is an adhesive sheet comprising a front base material and an adhesive layer provided on the back surface of the front base material, said adhesive sheet being characterized in that the adhesive layer is formed by applying an aqueous dispersion adhesive prepared by adding, as a plasticizer, a nonionic surfactant containing an amino group to an aqueous dispersion adhesive composition that contains 2-ethylhexyl acrylate, ethylenically unsaturated carboxylic acid and, as necessary, an acrylic copolymer obtained by emulsion polymerization of other polymerizable unsaturated monomers. The adhesive sheet has superior adherence between the front base material and adhesive layer, and the adhesion to adherends is superior. Furthermore, the adhesive sheet does not leave an adhesive residue on the adherend, even when peeled off after being adhered for a long period of time.
