Beschreibung
Zusammenfassung:	Provided is a method of manufacturing a battery module including a) aligning a first base material and a second base material, which are welding objects and housing members that are combined with each other to form an internal accommodating space in which a plurality of battery cells are accommodated and b) forming a welding joint portion including a bonding region and a surface region covering the bonding region by irradiating a contact surface between the first base material and the second base material with a laser, the bonding region and the surface region forming the welding joint portion having different microstructures due to different thermal history.
