1. A battery module comprises:
a battery cell stack in which a plurality of battery cells are stacked,
a U-shaped frame accommodating the battery cell stack and having an opened upper portion,
an upper plate covering the battery cell stack on the opened upper portion of the U-shaped frame,
a thermally conductive layer located between the U-shaped frame and the battery cell stack, and
a structural adhesive layer located between the upper plate and the battery cell stack,
wherein the thermally conductive layer is formed of a silicon-based thermally conductive paste, a liquid heat radiation material, or a thermally conductive compression pad, and the structural adhesive layer is formed of an epoxy-based material,
wherein the thermally conductive layer has a lower adhesive strength than the structural adhesive layer,
wherein the structural adhesive layer is applied on an upper end of the battery cell stack, and one end of each of the plurality battery cells included in the battery cell stack and the upper plate are coupled to each other in a direction perpendicular to a stacked direction of the plurality of battery cells.
