1. A battery module comprising:
a battery cell stack having a plurality of battery cells stacked in a stacking direction;
a module frame accommodating the battery cell stack;
a thermally conductive resin layer located between a lower surface of the module frame and the battery cell stack;
a first adhesive layer located between adjacent battery cells, among the plurality of battery cells;
a compression pad located between a side surface of the module frame and an outermost battery cell of the battery cell stack;
a second adhesive layer located between the outermost battery cell and the compression pad; and
a blocking film located between the battery cell stack and the thermally conductive resin layer,
wherein the second adhesive layer is formed offset from a central part of the battery cell stack and adjacent to the thermally conductive resin layer, wherein a liquid injection hole for injecting the thermally conductive resin layer is formed on the lower surface of the module frame, and the first adhesive layer is formed offset from the central part of the battery cell stack and adjacent to the thermally conductive resin layer.
