Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery pack in which battery performance degradation such as separator clogging or internal resistance rise in storage batteries hardly occurs even when the batteries forming the battery pack expand as a result of swelling and so forth of internal electrode plates forming an electrode body due to charge/discharge reaction or aged deterioration of the batteries.SOLUTION: A battery pack comprises: a plurality of batteries 300; and partition members 100 arranged at least on lateral sides of the batteries 300. The partition member 100 has an expansion/contraction region A1 which follows the expansion and contraction of the batteries 300.
