Abstract

Provided is a composition for a non-aqueous secondary battery functional layer with which it is possible to form a functional layer that can cause a battery component including the functional layer to display a balance of both high blocking resistance and high process adhesiveness. The composition for a non-aqueous secondary battery functional layer contains a particulate polymer having a core-shell structure including a core portion and a shell portion at least partially covering an outer surface of the core portion. The core portion is formed by a polymer A and the shell portion is formed by a polymer B including not less than 1 mass % and not more than 20 mass % of a cyano group-containing monomer unit.
