Abstract: Provided is a binder for a non-aqueous secondary battery that has excellent preservation stability and binding capacity, and that can suppress viscosity elevation of a slurry composition. The binder for a non-aqueous secondary battery contains a particulate polymer and water. The particulate polymer has a degree of swelling in an aqueous medium at pH 5 of less than a factor of 2 and has a degree of swelling in an aqueous medium at pH 8 of at least a factor of 2 and no greater than a factor of 7.
