Abstract: A battery module includes a plurality of battery blocks. Each battery block includes: a cell assembly including a plurality of cells; a block holder for holding the cell assembly; and a metal plate. The plurality of cells are held in the block holder while the positive electrodes and negative electrodes of the cells are aligned. A projection or the metal plate is disposed outside the block holder. The tip of the projection of one of adjacent battery blocks is in contact with the metal plate of the other.

Abstract: A battery block includes a plurality of cylindrical batteries, a battery holder that accommodates the cylindrical batteries arranged in a staggered manner, a positive-electrode current collector plate that is electrically connected to a positive electrode terminal of each of the cylindrical batteries, and a negative-electrode current collector plate that is electrically connected to a negative electrode terminal of each of the cylindrical batteries. At least one of the positive-electrode current collector plate and the negative-electrode current collector plate includes a bus bar that extends in an axial direction of the cylindrical battery to be electrically connected to a current collector plate of another battery block. A recess that accommodates the bus bar is formed in a gap between two of the cylindrical batteries in an end portion of the battery holder.
