Disclosed is a composition for non-aqueous secondary battery adhesive layer which comprises a particulate polymer and a binder, wherein the particulate polymer comprises 5% to 50% by mass of a (meth)acrylonitrile monomer unit and 0.1% to 3.5% by mass of a cross-linkable monomer unit. Also disclosed is a non-aqueous secondary battery adhesive layer prepared by using the composition for non-aqueous secondary battery adhesive layer. Also disclosed is a laminate which comprises a substrate and the non-aqueous secondary battery adhesive layer disposed on at least one side of the substrate either directly or indirectly through one or more other layers. Also disclosed is a non-aqueous secondary battery wherein at least one of a positive electrode, a negative electrode, and a separator comprises the non-aqueous secondary battery adhesive layer.
