PCT No. PCT/JP97/01397 Sec. 371 Date Dec. 23, 1997 Sec. 102(e) Date Dec. 23, 1997 PCT Filed Apr. 23, 1997 PCT Pub. No. WO97/40540 PCT Pub. Date Oct. 30, 1997The present invention provides a nonaqueous electrolyte battery 10 comprising a nonaqueous electrolytic solution 20 which is a nonaqueous electrolytic medium; positive and negative plates 30 and 32 in contact with the nonaqueous electrolytic medium; a first lead 18a having one end connected to the positive plate 30 and the other end extending to the outside; a second lead 18b having one end connected to the negative plate and the other end extending to the outside; and a sealing bag 14 for sealing the positive and negative plates 30 and 32, the nonaqueous electrolytic medium 20, and parts of the first and second leads 18a and 18b therein, the bag 14 being heat-sealed; wherein at least a heat-sealing portion 12 of the sealing bag 14 has a layer comprising a maleic acid modified polyolefin. The maleic acid modified polyolefin has a low hygroscopicity and a low compatibility with the nonaqueous electrolytic solution. Accordingly, high blocking properties against the nonaqueous electrolytic solution and steam are obtained, whereby the sealing bag 14 attains a high hermetic property.
