An object of the present invention is to provide a slurry composition for a functional layer capable of forming a functional layer that can be firmly adhered to a separator substrate and increasing rate characteristics of a secondary battery including a separator having the functional layer. The slurry composition for functional layers of the present invention contains a binder and a melamine compound. The binder is a polymer having at least one functional group selected from the group consisting of a carboxylic acid group, a hydroxyl group, an amino group, an epoxy group, an oxazoline group, a sulfonic acid group, a nitrile group, and an amide group, and the volume average of the melamine compound The particle diameter is 20 nm or more and 300 nm or less, and the proportion of the melamine compound in the total of the binder and the melamine compound is 0.5% by mass or more and 85% by mass or less. |
