Abstract
A battery module includes: a battery cell stack in which a plurality of battery cells are stacked; a module frame for accommodating the battery cell stack; and a heat sink formed on the lower side of the module frame to cool the plurality of battery cells. The heat sink includes a lower plate and a flow path part which defines a flow path for a refrigerant. The flow path part includes: a first path set that collects first flow paths formed in a direction perpendicular to the stacking direction of the battery cell stack; and a second path set that collects second paths formed in a direction parallel to the stacking direction of the battery cell stack, whereby a total length of the second path set is longer than a total length of the first path set.
