摘要：
A slurry for a lithium ion secondary battery porous membrane, including non-conductive particles, a water-soluble polymer containing an acidic group-containing monomer unit, and a particulate polymer, wherein: an amount of the water-soluble polymer is 0.05 parts by weight to 2 parts by weight relative to 100 parts by weight of the non-conductive particles; and a BET specific surface area of the non-conductive particles is 5 m2/g to 10 m2/g.
