Provided is a binder composition for a non-aqueous secondary battery electrode that enables production of a slurry composition that can be used in high-speed application and high-speed pressing and that enables formation of an electrode for a non-aqueous secondary battery that can cause a non-aqueous secondary battery to display excellent low-temperature cycle characteristics. The binder composition contains water and a particulate polymer that is formed of a polymer including a block region formed of an aromatic vinyl monomer unit. The particulate polymer has a volume-average particle diameter of not less than 0.08 μm and less than 0.6 μm.
