Abstract
A battery pack has a battery stack built therein. A case for the battery pack includes an upper case and a lower case. The upper case is not flat, but forms an arch shape having a curved surface. The upper case has a chamber space formed above the built-in battery stack, and cooling air taken in through an air intake port is supplied to the chamber space. The upper case formed in the shape of an arch prevents deformation of the chamber space against a load applied from above, and adjusts the cooling properties of the battery stack.
