Problem: To provide a resin composition that has excellent adhesiveness to bare copper, is capable of retaining adhesiveness to bare copper even when exposed to a hot and humid environment for a long period of time, and enables compliance to standards for high rated temperatures or accreditation to the standards to be achieved without involving a cross-linking step, and to provide a laminate that can be suitably used as a covering material for flexible flat cables in which the resin composition is used.
Solution: A resin composition for an adhesive layer of a laminate, the resin composition, containing: (A) 55 to 85 mass% of an acid modified polypropylene-based resin; and (B) 45 to 15 mass% of a copolymer of ethylene and one or more comonomers selected from the group consisting of vinyl acetate, an alkyl methacrylate, and an alkyl acrylate; in which the total of the component (A) and the component (B) is 100 mass%; and in which an acid modified amount of the component (A) is 0.5 to 10 mol%.
