摘要： Provided is a binder composition for a non-aqueous secondary battery that enables formation of a functional layer and an electrode mixed material layer having high transition metal capturing ability. The binder composition for a non-aqueous secondary battery contains a water-soluble polymer and water. The water-soluble polymer includes a sulfonate group-containing monomer unit in a proportion of at least 10 mass % and not more than 50 mass % and a (meth)acrylonitrile monomer unit in a proportion of 20 mass % or more.
