PROBLEM TO BE SOLVED: To provide an adhesive composition which yields an adhesive which may be applied without any inorganic solvent and shows a good corrugated board-sealing property at low temperatures, and provide a tape or a sheet to which the composition is applied. SOLUTION: This adhesive composition contains an acrylic emulsion polymer comprising a monomer mixture comprising from 60 to 98 wt.% (meth)acrylic monomer of formula (1): CH2=C(R1)COOR2, from 2 to 6 wt.% carboxyl group- containing vinyl monomer and from 0 to 38 wt.% functional group-containing vinyl monomer copolymerizable with these main monomers, which is obtained through emulsion polymerization using a monoalkyl succinate sulfonate as an emulsifier and has a gel percentage of from 46 to 58%, a weight average molecular weight of the sol content of >=500,000 and a glass transition temperature of from -75 to -55 deg.C.
