Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery pack device for preventing the application of excessive stress onto single cells. SOLUTION: In the battery pack device, the plurality of rectangular solid shaped single cells 1 and a plurality of plate shaped spacers 2 are alternately laminated, and pressed and constrained at both ends in the laminating direction. The spacers 2 each consist of a binder 21 having a positive linear expansion coefficient and a filler having a negative linear expansion coefficient. Preferably, the filler is a fibrous body 22 oriented along the laminating direction of the single cells 1 and the spacers 2. COPYRIGHT: (C)2010,JPO&INPIT
