PROBLEM TO BE SOLVED: To provide an adhesive composition which has a long pot life, excels in workability, attains to practical adhesive performance in a short aging time, and excels in productivity. SOLUTION: The adhesive composition includes: 100 pts.mass of a (meth)acrylic copolymer (A) having a weight average molecular weight of 100,000-2,000,000 and including a monomer component comprising 0-9 pts.mass of a carboxyl group-containing monomer, 0-9 pts.mass of a hydroxyl group-containing (meth)acrylic monomer, and 99.9-82 pts.mass of a (meth)acrylic acid ester monomer, a total amount of the carboxyl group-containing monomer and the hydroxyl group-containing (meth)acrylic monomer being greater than 0 pts.mass; 0.05-5 pts.mass of a carbodiimide crosslinker (B), based on 100 pts.mass of the (meth)acrylic copolymer (A); and 0.01-0.2 pts.mass of an imidazole compound (C) represented by chemical formula 1, based on 100 pts.mass of the (meth)acrylic copolymer (A). In chemical formula 1, R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>and R<SP POS="POST">3</SP>are each independently a hydrogen atom, a halogen atom, or a substituted or unsubstituted 1C-10C straight or branched alkyl group.
