A first cell block is configured to include a plurality of cells held in a first cell holder. A second cell block is configured to include a plurality of cells held in a second cell holder. The first cell holder and the second cell holder are disposed adjacent to each other in plan view from the cell longitudinal direction. A first line drawn connecting the center points of the plurality of cells disposed on the second cell holder side among the plurality of cells held by the first cell holder is parallel to a second line drawn connecting the center points of the plurality of cells disposed on the first cell holder side among the plurality of cells held by the second cell holder. |
