Provided is an acrylic adhesive composition, including: (A) 100 parts by mass of an acrylic polymer containing a carboxyl group, with a glass transition temperature of 5 to 30° C., (B) 1 to 20 parts by mass of a resol-type phenol resin, (C) 1 to 20 parts by mass of an epoxy resin, and (D) 10 to 100 parts by mass of an inorganic filler, the composition optionally including 0 to 0.5 parts by mass of a curing accelerator per 100 parts by mass of the component (A). Also provided are an acrylic adhesive sheet that contains an adhesive layer including this composition and a method of bonding two substrates using this acrylic adhesive sheet. The acrylic adhesive sheet exhibits excellent adhesiveness, heat resistance, workability, handling properties and storage stability, and the acrylic adhesive composition is useful in the production of such an adhesive sheet.
