To provide a novel battery module which is improved to cause less inconvenience.SOLUTION: A battery module according to the present embodiment, for example, comprises: a battery cell, a housing, and a heat absorption member. The battery cell has: a first face from which an electrode part is exposed; a second face intersecting the first face; and a third face facing opposite to the first face. The housing has: a first wall part which extends along the third face and covers the third face; and a fluid cooling path extending along the second face. The heat absorption member is provided so as to be thermally connected to the third face. The heat absorption member has a heat capacity higher than that in a region, on the first wall part, overlapping the third face in a first direction along the thickness of the first wall part.SELECTED DRAWING: Figure 4 【課題】より不都合が少なくなるよう改善された新規な電池モジュールを得る。【解決手段】実施形態の電池モジュールは、例えば、電池セルと、筐体と、熱吸収部材と、を備える。電池セルは、電極部が露出した第一の面と、第一の面と交差した第二の面と、第一の面とは反対側を向いた第三の面と、を有する。筐体は、第三の面に沿って延びるとともに当該第三の面を覆う第一の壁部を有し、第二の面に沿って延びる流体の冷却通路が設けられる。熱吸収部材は、第三の面と熱的に接続された状態に設けられ、第一の壁部のうち第三の面と第一の壁部の厚さに沿う第一の方向に重なる領域での熱容量よりも大きい熱容量を有する。【選択図】図４
