Abstract: The present invention provides an adhesive composition that shows good adhesion to a polyolefin resin substrate and a metal substrate, and good electrolyte solution resistance, and also exhibits excellent heat resistance. The present invention also provides a laminate including an adhesive layer comprising the adhesive composition, a packaging material using the laminate for which heat resistance and electrolyte solution resistance are required, and a packaging material for a lithium-ion battery comprising the laminate as a constituent member. The adhesive composition comprises an acid-modified polyolefin (A), an isocyanate curing agent (B), and an acid anhydride group-containing compound (C), the acid anhydride group-containing compound (C) being present in an amount of 0.1 parts by mass or more and 20 parts by mass or less based on 100 parts by mass of the acid-modified polyolefin (A).
