PURPOSE: A battery pack is provided to improve work efficiency by optimizing the movement line of an automatic welder and arranging a plurality of secondary battery cells to have optimal spatial arrangement. CONSTITUTION: A battery pack comprises a stack(100) and a conductive plate(200). The stack comprises a plurality of cells(110). On a basis of the upper side or bottom side of the cells, at least two cells are arranged in a short axis direction and a plurality of cells are arranged so that the center connection line of the cell adjacent to a long axis direction is not perpendicular to a short axis direction. The conductive plate electrically connects at least two cells adjacent to the upper side and the bottom side of the cells. |
