Abstract

Provided is a binder composition for a non-aqueous secondary battery with which it is possible to form a functional layer that can provide a battery component such as an electrode or a separator with a balance of excellent handleability and process adhesiveness. The binder composition for a non-aqueous secondary battery contains: polymer particles containing a block polymer including a block region composed of an aromatic vinyl monomer unit; a water-soluble polymer including a hydrophilic group; and water. The block polymer has a diblock content of not less than 0 mass % and not more than 60 mass %. The water-soluble polymer has a weight-average molecular weight of not less than 15,000 and not more than 500,000.
