Provided is an aqueous slurry composition for the positive electrode of a lithium ion secondary battery, which can suppress both the generation of pin holes and the occurrence of bulging along the edge portion of a positive electrode active material layer. The slurry composition for the positive electrode of a lithium ion secondary battery includes a positive electrode active material, a conductive material, a viscosity modifier, a particulate binder, a surfactant, and water. The surfactant contains a polyoxyethylenic surfactant (a) and a sulfosuccinic acid ester or its salt (b). |
