Abstract
A power supply device includes battery cells, separators, and fastening members. The plurality of battery cells have a rectangular-box exterior shape. The separators are interposed between the battery cells, which are arranged side by side. The fastening members securely hold a battery assembly of the battery cells and the separators, which are alternately arranged side by side. The surfaces of each of the battery cells is covered by an electrically insulating covering member. Each of the separators has recessed parts that form a plurality of gas-flowing paths between the battery cells so that cooling gas can flow along surfaces of these battery cells when this separator is interposed between these battery cells. Edge parts of the recessed part, which forms the gas-flowing paths, are rounded.
