An object of the present invention is to provide a laminating adhesive composition for a laminate, the composition having excellent adhesion between a metal layer and a plastic layer of a laminate, electrolyte solution resistance even after low-temperature aging, and a high retention percentage of the resistance, and allowing no delamination between layers to occur over time; a method for producing the laminating adhesive composition; a laminate using the adhesive; and a secondary battery. The object is achieved by providing a laminating adhesive containing a polyolefin resin (A) and an epoxy compound (B). The polyolefin resin (A) is a polymer in which propylene and 1-butene are the main monomers and has a crystallization peak temperature within the range of 28 C. to 38 C.
