Abstract: A battery pack has a sealed case. Battery modules are accommodated in the sealed case. An opening in the main body is closed by a rectangular plate-shaped lid member. The lid member has a releasing portion and a joint portion. When the internal pressure of the sealed case increases, the lid member is deformed away from an opening edge of the opening. This discharges gas from the sealed case through the releasing portion. In addition, the joint between the joint portion and the opening edge is maintained even when the internal pressure of the sealed case increases, deforming the releasing portion, and the gas inside the sealed case starts to be discharged. A protrusion of a rib is provided between the releasing portion and the joint portion.
