PROBLEM TO BE SOLVED: To provide a battery module and a battery device of novel configuration, e.g., local stress occurring in a plate can be reduced more.SOLUTION: A battery module includes battery cells, a plate, a coupling member and a support member, for example. Each of multiple battery cells has a first face provided with an external connection terminal, and a second face on the opposite side to the first face. The plate is located between two battery cells. The coupling member couples multiple battery cells and the plate in a first direction so that multiple first faces are aligned and multiple second faces are aligned. The support member has a third face provided with a recess housing one end of the plate, and facing the multiple second faces while leaving a gap, and a support adjacent to the recess and projecting from the third face to the second face along the plate and supporting the plate.SELECTED DRAWING: Figure 1 【課題】例えば、プレートに生じる局所的な応力がより低減されやすい新規な構成の電池モジュールおよび電池装置を得る。【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、プレートと、結合部材と、支持部材と、を備える。複数の電池セルは、外部接続端子が設けられた第一の面と、第一の面とは反対側の第二の面と、をそれぞれ有する。プレートは、二つの電池セルの間に位置される。結合部材は、複数の電池セルとプレートとを、複数の第一の面が並びかつ複数の第二の面が並ぶように、第一の方向に沿って列状に結合する。支持部材は、プレートの第一の端部を収容した凹部が設けられ、複数の第二の面と隙間をあけて面した第三の面と、凹部と隣接し第三の面からプレートに沿って第二の面側に突出してプレートを支持する支持部と、を有する。【選択図】図１
