A battery pack in which adjoining battery modules are electrically connected is provided with higher reliability of connection and at lower cost than before. A battery pack comprises a plurality of battery modules each including a plurality of sealed batteries. Of the battery modules, a first connecting cell of a first battery module and a second connecting cell of a second battery module are disposed each other in adjoining relation. An external positive terminal of the first connecting cell, serving as a positive electrode, and a second side surface of the second connecting cell, serving as a negative electrode, are electrically connected with each other by a connecting member having extended parts and a plate-like part.
