Battery module

A battery module comprising:

• a plurality of battery cells stacked in a first direction;
• and
• a spacer disposed between the plurality of battery cells adjacent to each other,
• wherein each of the plurality of battery cells includes a rectangular battery case containing an electrode body and an electrolyte solution therein,
• the spacer includes a pressing portion configured to press the plurality of battery cells in the first direction by making contact with a predetermined pressing region of an outer surface of the rectangular battery case,
• the pressing region, as viewed from the first direction, is configured to overlap a central portion of the electrode body and not to overlap both end portions of the electrode body in a width direction of the battery cell, and
• the pressing portion, when viewed from the first direction, has a shape in which a portion overlapping a lower side portion than the central portion of the electrode body is larger than a portion overlapping an upper side portion than the central portion of the electrode body.
