The battery pack comprises two or more battery cells; and a cell holder in which the battery cells are assembled, and which includes a base part extended in the alignment direction of the battery cells to intersect with the battery cells, and a side part downwardly extended from the base part to cover lateral surfaces of the battery cells. An extended end of the side part includes a skirt surface which protrudes more than the lateral surfaces of the battery cells. According to the present invention, for the cell holder which structurally connects the battery cells, a stable support base for welding is provided. So, the battery pack with improved welding workability can be provided. |
