The object of the present invention is to provide a non-aqueous secondary battery functional layer composition, which can form a non-aqueous secondary battery that combines excellent pressure-sensitive adhesiveness and anti-blocking properties, and enables the secondary battery to exhibit excellent cycle characteristics. Functional layer for batteries. The non-aqueous secondary battery functional layer composition of the present invention comprises a polymer and a solvent, the above-mentioned polymer is a block copolymer containing an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit, and the above-mentioned polymer The amount of diblock is 5% by mass or more and 85% by mass or less. |
