Abstract
Provided is a battery pack that, even in a case in which a metal plate and an electrode terminal are made of different metals, can increase reliability of the connection strength by welding them and can be configured at a low cost. A battery packincludes adjacent battery cellshaving positive and negative electrode terminals connected each other by a metal plate, and a dissimilar material bonding platehaving a terminal insertion holeis disposed above a terminal connection hole, which is a long hole or a loose hole, into which an electrode terminalcomposed of a different kind of metal from the metal plate. The dissimilar material bonding plateincludes a stack of a first plateand a second platethat are composed of different kinds of metal from each other, and an outer diameter of the second plateis larger than that of the first plate, in which the first plateis composed of a metal of the same element as a metal that forms the electrode terminal, and welded to the electrode terminal, and the second plateis composed of a metal of the same element as a metal that forms the metal plate, and welded to the metal plate
