Abstract
Provided is a composition for a non-aqueous secondary battery functional layer that has excellent redispersibility of non-conductive particles and enables formation of a functional layer for a non-aqueous secondary battery having excellent flexibility. Also provided are a functional layer for a non-aqueous secondary battery formed using this composition for a non-aqueous secondary battery functional layer and a non-aqueous secondary battery including this functional layer for a non-aqueous secondary battery. The composition for a non-aqueous secondary battery functional layer contains non-conductive particles, a water-soluble polymer that includes a (meth)acrylamide monomer unit in a proportion of 40 mass % or more and has a weight average molecular weight of less than 3.0×10, and a particulate polymer.
