Abstract: Provided is a binder composition for an electrical storage device that can both ensure stability of a slurry composition and enhance peel strength of an electrode and rate characteristics of an electrical storage device. The binder composition contains a particulate polymer. The particulate polymer includes a cyano group-containing monomer unit in a proportion of not less than 5 mass % and not more than 45 mass % and includes an amide group-containing monomer unit in a proportion of not less than 0.3 mass % and not more than 10 mass %. Moreover, the particulate polymer has a core-shell structure including a core portion and a shell portion at least partially covering an outer surface of the core portion, and has at least one glass-transition temperature at 10° C. or lower.
