Abstract
A battery module includes battery cells each of which includes a pair of broad width surfaces and that are arranged such that the broad width surfaces are opposed to each other and a heat insulator arranged between an adjacent pair of battery cells. The heat insulator includes a heat insulating sheet and a buffer sheet bonded to the heat insulating sheet. The heat insulating sheet is formed of a material that can be more easily compressively deformed than the heat insulating sheet. The heat insulating sheet includes a recessed portion in a surface to which the buffer sheet is bonded.
Claims8
