摘要： Provided is an adhesive composition comprising a modified polyolefin and an epoxy resin, the composition having excellent pot life, and excellent adhesion to both a metal substrate and a polyolefin resin substrate. The adhesive composition comprises a modified polyolefin (A), a glycidyl amine-type epoxy resin (B1), a glycidyl ether-type epoxy resin (B2), and an organic solvent (C); wherein the modified polyolefin (A) is (A1) or (A2) below: (A1): a crystalline acid-modified polyolefin having an acid value of 5 to 50 mg KOH/g-resin; or (A2): an acid-modified chlorinated polyolefin having an acid value of 5 to 50 mg KOH/g-resin and a chlorine content of 5 to 40 mass %.
