• and
• a module case for holding the cell-stacked body, wherein
• the module case includes
• a pair of side plates for holding side surfaces of the cell-stacked body,
• a bottom plate on which the cell-stacked body is loaded, and
• a plate member installed on an upper end portion of the pair of side plates to cover at least a part of an upper surface of the cell-stacked body,
• a filler is filled in a first space formed between the plate member and the upper surface of the cell-stacked body and in a second space formed between the side plate and the side surface of the cell-stacked body,
• the plate member includes an injection hole through which the filler is injected,
• the injection hole is arranged at a location overlapping with the upper surface of the cell-stacked body,
• a guide passage member is provided between the plate member and the upper surface of the cell-stacked body, the guide passage member guiding the filler injected through the injection hole to the second space in an obliquely downward direction, and
• the guide passage member includes an inclined guide that guides the filler injected through the injection hole to flow over a surface of the inclined guide, in the obliquely downward direction, and into the second space.
