Abstract
Provided is a composition for a non-aqueous secondary battery porous membrane capable of forming a porous membrane having excellent peel strength and capable of providing a non-aqueous secondary battery having excellent output characteristics. The composition for a non-aqueous secondary battery porous membrane contains inorganic particles, a binder, a surfactant, and water. The binder includes a polymer including an aromatic vinyl monomer unit. Fractional content of the surfactant is not less than 0.25 parts by mass and not more than 5 parts by mass per 100 parts by mass of the inorganic particles.
