• a fuse,
• a first bus bar connected via the fuse to one electrode, from among the positive electrode and the negative electrode,
• a second bus bar directly connected to the other electrode, from among the positive electrode and the negative electrode, and
• a retaining member configured to retain the plurality of single cells from the radial direction of the single cell, in a manner such that when the fuse is disconnected, retaining force with which the single cell is retained by the retaining member decreases and the single cell moves in a direction away from the fuse;
