却性能が低下してしまう。However, these assembled batteries have a problem in that sufficient cooling performance cannot be obtained. As described in Japanese Patent Application Laid-Open No. 9-199094, in a battery pack of a type in which a rib or a convex portion is formed in a case to form a flow path of a cooling medium, the thickness of the rib is reduced by reducing the thickness in order to enhance the cooling effect. If the interval between the protrusions is widened, sufficient strength cannot be obtained, and the case is deformed due to a change in internal pressure during charging and discharging, and the performance is reduced due to the deformation. If the spacing between the ribs and the projections is reduced in order to restrict such deformation of the case, the contact area with the cooling medium is reduced, and the cooling effect is reduced. Further, when the width of the rib or the convex portion is reduced, the rib or the convex portion may be crushed when the lamination position is slightly shifted due to a manufacturing error or an assembly error, and in this case, sufficient strength may be maintained. However, a desired cooling effect cannot be obtained. As described in Japanese Patent Application Laid-Open No. 5-343105, in a battery pack of a type using a spacer having a through-hole as a flow path of a cooling medium, the strength can be maintained by the spacer. However, since the spacer has the side plates, the battery cannot be directly cooled, and the cooling performance is reduced.
