Abstract
Provided is a battery pack that ensures sufficient sealing performance between a tray and a cover by arranging a necessary sealing member between a lower flange portion of the tray and an upper flange portion of the cover that are held in abutment with each other. The tray and the cover covering the tray constitute a packaging case of electric cells. At least a part of a facing surface of at least one of the lower flange portion of the tray and the upper flange portion of the cover that abut each other forms a non-abutting portion that is located apart from the facing surface of the opposite flange portion, and a sealing member is arranged on the non-abutting portion.
