<p>[Problem] To accommodate a large number of secondary battery cells while keeping the cost low. [Solution] A cell holder (20) is divided, in the direction of the length of the cell accommodation units, into a first divided holder (21), a second divided holder (22), and a third divided holder (23). The first divided holder (21), second divided holder (22), and third divided holder (23) are formed by injection molding. The first divided holder (21) is fixed to the inner surface of a first divided case (12A), the second divided holder (22) is fixed to the inner surface of a second divided case (12B), and the third divided holder (23) is interposed between the first divided holder (21) and the second divided holder (22). The first divided holder (21), third divided holder (23), and second divided holder (22) are combined, thereby forming a plurality of cell accommodation units and making it possible to accommodate the secondary battery cells (11).</p> |
