PURPOSE: A unit module is provided to steadily fix a battery cell by a polymer resin through filling the polymer resin inside an exterior unit, thereby minimizing an impact to the battery cell by external force. CONSTITUTION: A unit module comprises: two or more battery cells which have a structure where battery cells are mounted in a battery case and the outer circumference is sealed, and in which electrode terminals are laminated to be connected to each other in series or in parallel; a pair of exterior members(200,200a) which are coupled to each other to surround the whole outside of the battery cell laminate; and a polymer resin(140) which is filled inside the exterior members in a state of being attached to the lateral sealing part(144) of the outer circumference and the inner side of the exterior members. |
