Claim 0:
1. A binder composition for a non-aqueous secondary battery comprising: a particulate polymer formed of a polymer that includes a block region formed of an aromatic vinyl monomer unit; water-soluble macromolecules; and water, wherein
surface acid content A of the particulate polymer per 1 g of the particulate polymer is 0.05 mmol/g or more,
acid content B in an aqueous phase of the binder composition per 1 g of the particulate polymer is not less than 0.03 mmol/g and not more than 0.80 mmol/g, and
a ratio A/B of the surface acid content A of the particulate polymer and the acid content B in the aqueous phase of the binder composition is not less than 0.5 and not more than 5.0.
