Battery module

A battery module (100) includes a plurality of battery cells (10) arranged in one direction, barriers (150) interposed between the respective battery cells (10), and a housing (110) accommodating the battery cells (10) and the barriers (150). The barrier (150) includes a base plate (151) disposed in parallel with wide surfaces of the battery cell (10), and one or more plates (153, 155, 157) extending perpendicular to the base plate (151) so as to face a side surface of the battery cell (10). At least one of the plates (153, 155, 157) is provided with a plurality of spacing members (160, 170) respectively protruding from outer and inner surfaces of the plates (153, 155, 157).
