Abstract: A battery pack includes: a plurality of battery cells in a plurality of columns, the battery cells in each of the columns being located along a column direction, and the battery cells in the columns adjacent to each other being located along a zigzag pattern in a row direction while alternately shifted forward and rearward in the column direction; a plurality of cooling pieces, each of the cooling pieces being located between the battery cells in the columns adjacent to each other, and extending in a meander shape along an outer circumference of the battery cells in the columns adjacent to each other; and a bus bar on a terminal surface of the battery cells to electrically connect the battery cells to each other in rows adjacent to each other, the terminal surface being a surface on which different first and second electrodes are exposed.
