Provided is a slurry composition for a non-aqueous secondary battery functional layer with which it is possible to form a functional layer that has excellent adhesiveness and that can improve rate characteristics of a non-aqueous secondary battery. The slurry composition for a non-aqueous secondary battery functional layer contains organic particles, a binder, and a melamine compound. The melamine compound constitutes a proportion of not less than 0.5 mass % and not more than 85 mass % among the total of the binder and the melamine compound.
