Abstract: Provided is a slurry composition for a non-aqueous secondary battery positive electrode that has excellent stability and enables formation of a positive electrode mixed material layer that causes a non-aqueous secondary battery to display excellent output characteristics. The slurry composition contains a positive electrode active material and a copolymer. The proportion constituted by nickel among transition metal in the positive electrode active material is at least 30.0 mol % and not more than 100.0 mol %. The copolymer includes a nitrile group-containing monomer unit in a proportion of at least 70.0 mass % and not more than 96.0 mass % and a basic group-containing monomer unit in a proportion of at least 0.1 mass % and not more than 5.0 mass %.
