Abstract
Disclosed is a battery pack, which includes a plurality of cell assemblies respectively having a cell housing for accommodating battery cells and arranged in a front and rear direction; a first metal plate mounted at a top portion of the cell housing and integrally contacting upper electrode terminals of the battery cells; and a second metal plate mounted at a bottom portion of the cell housing and integrally contacting lower electrode terminals of the battery cells. The cell housing includes a side portion that has a slit forming a gap into which a part of the first metal plate and a part of the second metal plate are bent and inserted in an upper and lower direction and a perforated hole formed in a direction intersecting the slit. The bent part of the first metal plate mounted to any one cell housing is overlapped with the bent part of the second metal plate mounted to another the cell housing adjacent thereto inside the perforated hole.
