摘要： Disclosed is a nonaqueous electrolyte battery using an aqueous sealant composition. The aqueous sealant composition comprises an aqueous dispersion in an amount of 70 mass % or more and 97 mass % or less by mass of solid content, wherein the aqueous dispersion comprises an olefinic polymer as a main component, and a water-soluble polymer in an amount of 3 mass % or more and 30 mass % or less by mass of solid content. The aqueous dispersion comprises an olefinic polymer as a main component. The olefinic polymer is a modified olefinic polymer. The modified olefinic polymer is a partial copolymer of a polymer selected from a group consisting of polyethylene, polypropylene, polybutene and ethylene-propylene polymers, and a polymerizable unsaturated organic acid selected from a group consisting of maleic anhydride, acrylic acid, methacrylic acid and esters thereof.
