CONSTITUTION: A battery module includes a module case (110) and plural unit cells (120) arranged inside the module case, and is formed by the combination of the module case and the unit cells. The battery module includes an assembly error prevention unit for aligning the assembly orientation of the unit cells into a uniform pattern toward the arrangement direction of the unit cells. The assembly error prevention unit is formed into a pair on the diagonal directions of the unit cells. [Reference numerals] (AA) Insertion direction |
