A battery module includes a battery cell assembly having a plurality of battery cells, a sensing assembly which covers a front and rear of the battery cell assembly when mounted thereto, a module case which receives the battery cell assembly and the mounted sensing assembly, and a thermally conductive adhesive interposed between an upper inner surface of the module case and an upper side of the battery cell assembly. The sensing assembly includes a first busbar frame assembly positioned at the front of the battery cell assembly, a second busbar frame assembly positioned at the rear of the battery cell assembly, and a sensing wire which connects the first and second busbar frame assemblies and runs across the upper side of the battery cell assembly in a diagonal direction. The thermally conductive adhesive is disposed on two sides of the sensing wire.
