BATTERY MODULE AND METHOD FOR MANUFACTURING BATTERY MODULE

A battery module includes a battery cell, a heat exchange member having a flow path through which a heat medium flows, and a holding member that holds a positional relationship between the battery cell and the heat exchange member, in which, assuming that a direction, in which the battery cell and the heat exchange member are arranged side by side, is an arrangement direction and a surface of the battery cell facing the heat exchange member side is a heat exchange member side facing surface: the heat exchange member side facing surface has a shape having unevenness in the arrangement direction; and the heat exchange member has higher flexibility than the heat exchange member side facing surface, and is pressed toward the heat exchange member side facing surface side by the holding member in a state of being deformed following the shape of the heat exchange member side facing surface.
