Abstract
A composition for a non-aqueous secondary battery adhesive layer contains organic particles and a water-soluble polymer. The water-soluble polymer has a 1 mass % aqueous solution viscosity of at least 500 mPa·s and not more than 9,000 mPa·s. Viscosity η0 of the composition for a non-aqueous secondary battery adhesive layer at a shear rate of 100 s−1 is at least 10 mPa·s and not more than 200 mPa·s, and a ratio of η0 relative to viscosity η1 of the composition for a non-aqueous secondary battery adhesive layer at a shear rate of 10,000 s−1 is at least 1.5 and not more than 5.0.
