Summary: | Provided is a binder for a secondary battery functional layer that can form a functional layer having excellent heat shrinkage resistance and electrolyte solution affinity. The binder for a secondary battery functional layer contains a particulate polymer including a cyano group-containing monomer unit, a cyclic ether-containing monomer unit, and a carboxyl group-containing monomer unit. The proportional content of the cyclic ether-containing monomer unit in the particulate polymer is 5 mass% or more. |
