PROBLEM TO BE SOLVED: To prevent corrosion of a case of nonaqueous electrolyte batteries, in regard to a battery pack wherein the battery pack of the nonaqueous electrolyte batteries is stored in an electronically conductive case body. SOLUTION: This battery pack includes the battery pack 2 having a unit constituted by connecting in series the plurality of flat-type nonaqueous electrolyte batteries each of which is provided with the case 4 made of a laminated film with a layer 8 of aluminum or aluminum alloy and having a seal part in at least part of the circumference and with electrodes 17 stored inside the case 4 and including a negative electrode active material in which lithium storage potential (open circuit) is above 0.4 V with respect to lithium metal potential; and the electronically conductive case body 1 in which the battery pack 2 is stored. Portions 21a, 21b, out of end faces of the seal part of the case 4, opposing to the wall faces of the case body are insulated from the case body 1. COPYRIGHT: (C)2008,JPO&INPIT
