Zusammenfassung:	A battery pack includes a secondary battery cell having a surface including a safety valve, a housing including a first case and a second case which are divided, and a fire-resistant plate disposed inside the housing and on a surface of the housing facing the surface of the secondary battery cell. The housing includes a fire-resistant-plate-disposition surface on which the fire-resistant plate is disposed inside the housing, and a hole region in which first through-holes are provided therein. The hole region is provided in each of side surfaces of the housing intersecting the fire-resistant-plate-disposition surface at both sides of the fire-resistant-plate-disposition surface. The parting line is positioned at a middle of the fire-resistant-plate-disposition surface of the housing away from corners of the fire-resistant-plate-disposition surface of the housing, and positioned along a perimeter of the hole region in each of the side surfaces of the housing.
