Abstract
A battery case of an electric vehicle includes a drain hole for discharging water in the interior to the outside and a water detection device disposed in the vicinity of the drain hole. At least part of an upper face of a case bottom wall of the battery case is inclined downward toward the drain hole. Accordingly, not only is it possible to mold the downward inclination of the upper face of the case bottom wall of the battery case easily at the time of die casting without increasing the number of components, but it is also possible to guide water that has entered the interior of the battery case smoothly toward the drain hole, detect it reliably by the water detection device, and discharge it quickly via the drain hole.
