Summary:To provide a battery module capable of suppressing an increase in manufacturing cost and reducing a hight dimension of the battery module.SOLUTION: A battery module 1 includes a cell laminate 2 configured by laminating a plurality of cells 21 and a module case 3 for holding the cell laminate 2. The module case 3 includes a pair of side plates 5 for holding side faces of the cell laminate 2, a bottom plate 6 on which the cell laminate 2 is placed and a plate member 7 placed on the upper end portions of the side plates 5 and covering at least a part of the upper surface of the cell laminate 2. A gap S1 formed between the plate member 7 and the upper surface of the cell laminate 2 and gaps S2 formed between the side plates 5 and the cell laminate 2 are filled with a filler material 8.SELECTED DRAWING: Figure 3 【課題】製造コストの増加を抑制し、バッテリモジュールの高さ寸法を小さくできるバッテリモジュールを提供する。【解決手段】複数のセル21が積層されたセル積層体2と、該セル積層体2を保持するモジュールケース3と、を備えるバッテリモジュール1であって、モジュールケース3は、セル積層体2の側面を保持する一対のサイドプレート5と、セル積層体2が載置されるボトムプレート6と、サイドプレート5の上端部に設けられ、セル積層体2の上面の少なくとも一部を覆うプレート部材7と、を備える。プレート部材7とセル積層体2の上面との間に形成される隙間S1、及びサイドプレート5とセル積層体2の側面との間に形成される隙間S2には、充填剤8が充填されている。【選択図】図3
