PROBLEM TO BE SOLVED: To provide a water-dispersible pressure-sensitive adhesive composition useful for manufacturing a pressure-sensitive adhesive sheet high in coarse face adhesiveness and excellent in balance with other characteristic, and for other application.SOLUTION: The water-dispersible pressure-sensitive adhesive composition contains an acrylic polymer pAx, and an acrylic polymer pAy having 1×10-50×10of Mw at 100 : 6-35 of mass ratio. The pAx is a copolymer copolymerised with 60-99.5 mass% of 2-18C alkyl (meth)acrylate M1x, and 0.5-12 mass% of functional group containing monomer M2x, and the pAy is a copolymer copolymerised with 60-95 mass% of 2-18C alkyl (meth)acrylate M1y, and 5-40 mass% of functional group containing monomer M2y. A solubility difference ▵SP defined by |SPy-SPx| is 0.25 (cal/cm)or more, where SPx and SPy represent solubility parameters calculated based on compositions of the M1x and the M1y.
