Disclosed is an adhesive composition containing: an acrylic copolymer (A) having a hydroxyl group and carboxyl group, a weight average molecular weight of 700,000 to 2,000,000, and a theoretical Tg of -40°C or lower, including as constituent components 50-90 mass% of a (meth)acrylic acid alkyl ester (A1) having an alkyl group having 4-12 carbon atoms, 3-20 mass% of a carboxyl group-containing monomer (A2), 3-20 mass% of a hydroxyl group-containing monomer (A3), and 3-15 mass% of a (meth)acrylic acid alkyl ester (A4) having an alkyl group having 1-3 carbon atoms; and a crosslinking agent (B). Also disclosed is one-sided or double-sided adhesive tape using said composition. |
