1. A connection module to be mounted on a power storage element group including power storage elements having electrode terminals and connecting the power storage elements, the connection module comprising:
a flexible printed circuit board;
connection members connected to the flexible printed circuit board and connecting the electrode terminals of the power storage elements that are adjacent to each other, wherein
the flexible printed circuit board includes connection member mount portions to which the connection members are connected, and an expandable/contractable portion that is continuous from one connection member mount portion out of the connection member mount portions and allowed to be expanded and contracted in a direction to be closer to and farther away from another connection member mount portion out of the connection member mount portions that is adjacent to the one connection member mount portion, and wherein
the flexible printed circuit board has a slit provided between the one connection member mount portion and the expandable/contractable portion; and
a holding member that holds the connection members and the flexible printed circuit board, wherein the holding member includes a rib that is inserted into the slit.
