A battery module includes a cell stack in which a plurality of battery cells is stacked along a predetermined stacking direction. A pair of end plates are disposed on both end faces of the cell stack in the stacking direction. A mid-plate is disposed in an intermediate portion of the cell stack and has a pair of main faces facing the battery cell, —a plurality of side faces each connecting outer edges of the pair of main faces, and a recess on at least one of the side faces, the recess extending in a cross direction that intersects the stacking direction. A first belt has an outer belt portion disposed outside of the end plate in the stacking direction and an inner belt portion disposed in the recess, the first belt holding the battery cells stacked between the end plate and the mid-plate from both sides in the stacking direction.
