An aqueous pressure-sensitive adhesive composition of the invention comprises a rubber-based latex and a tackifier resin emulsion, wherein the tackifier resin emulsion is that obtained by emulsifying a tackifier resin in the presence of an emulsifier containing an ammonium salt of rosins; and the aqueous pressure-sensitive adhesive composition contains a water-soluble salt of casein as protective colloid. The aqueous pressure-sensitive adhesive composition is excellent in mechanical stability and insulating characteristics and has good moisture-proof adhesive strength.
