Provided is a secondary battery module, which shows a reduced contact resistance between electrode terminals by improving the structure of a washer disposed between electrode terminals. The secondary battery module(100) comprises: a plurality of unit cells(10) having electrode terminals(21,22) protruding to the exterior; a linking member(30) for electrically connecting the unit cells with each other; nuts(25,26) coupled to the electrode terminals for supporting the linking member; and washers(32,33) interposed between the nut and the linking member and having protrusions formed on at least one surface thereof. The protrusions are formed on the surface which is in contact with the linking member. |
