1. A battery module comprising:
a battery cell stack in which a plurality of battery cells are stacked;
a busbar frame connected to the battery cell stack;
a busbar;
cell terraces each protruding from mutually adjacent battery cells among the plurality of battery cells included in the battery cell stack; and
electrode leads each protruding from the cell terraces and having the same polarity;
wherein at least one of the cell terraces defines a bending portion that contacts the busbar,
wherein the busbar comprises a first surface facing the battery cell stack, and a second surface located on an opposite side to the first surface,
the at least one of the cell terraces that defines the bending portion passes through a slot formed in the busbar from the first surface and is bent on the second surface to form the bending portion.
