Zusammenfassung:	Provided is a slurry composition for a lithium ion secondary battery that can cause an electrode for a lithium ion secondary battery to display excellent adhesiveness (peel strength) and flexibility (pliability) and that can cause a lithium ion secondary battery to display excellent rate characteristics and cycle characteristics. The slurry composition for a lithium ion secondary battery contains a silicon compound and a binder. The silicon compound includes either or both of Li2SiO3 and Li4SiO4. The binder includes a water-soluble polymer that includes either or both of an ethylenically unsaturated carboxylic acid monomer unit (A) and an alkali metal salt thereof, and that includes a cross-linkable monomer unit (B). A 1 mass% aqueous solution of the water-soluble polymer has a viscosity of 1,000 mPa·s or less. The slurry composition for a lithium ion secondary battery has a pH of not lower than 9 and not higher than 12.
