An inter-module passage 12 is constructed between the adjacent battery modules. An inter-cell passage 11 is constructed between the adjacent battery cells. The housing body includes: a fetching part 17A that fetches an air blow from the air blower; and a transmission part 16 that transmits the air fetched from the fetching part and passed through the inter-module passage and the inter-cell passage. The inter-module passage includes a first inter-module passage 12A into which the air before fetched from the fetching part and passes through the inter-cell passage is inserted. The transmission part is separated from the first inter-module passage through at least one battery module so that the air is passed in the inter-cell passage of each of the plurality of adjacent battery modules while nipping the first inter-module passage.SELECTED DRAWING: Figure 2
