Abstract: A bus bar has: a first joint part connected to an output terminal of the first cell; a second joint part connected to an output terminal of the second cell; and a projection that is disposed between the first joint part and the second joint part and protrudes in a stacking direction in which the cells and the bus bar are stacked. The projection has a first inclined part extending from the first joint part and has a second inclined part extending from the second joint part. The first inclined part and the second inclined part are arranged in such a manner that the first inclined part and the second inclined part are aligned with a predetermined interval W and that the predetermined interval gradually becomes wider from a first end side toward a second end side.

Abstract: A battery module including a plurality of batteries, and a busbar electrically connecting the batteries. The battery includes: a battery can including a cylindrical portion, a bottom wall closing one end of the cylindrical portion, and an open rim continuing to the other end of the cylindrical portion; an electrode body; and a sealing body which seals an opening defined by the open rim. The sealing body has a first principal surface facing an interior of the battery can, a second principal surface opposite to the first principal surface, and a side surface connecting the first principal surface with the second principal surface. The busbar has a plurality of through-holes fitted with the batteries. The open rim of each of the batteries fitted into the through-holes is at least partially in contact with the busbar. The sealing body and the busbar are electrically insulated from each other.
