Zusammenfassung:	There are provided a battery module and a method of manufacturing the same. The battery module includes a plurality of battery cells, a bus-bar and a reflective portion. Each of the plurality of battery cells is provided with a terminal portion. The bus-bar is welded to the terminal portion to electrically connect between the plurality of battery cells, and has an opening formed therein. The reflective portion is positioned on the terminal portion so that at least one portion of the reflective portion is exposed through the opening. Accordingly, laser is reflected by the reflective portion, so that the welding portion between the bus-bar and the terminal portion is firmly formed.
