1. A connection module that is attached to a power storage element group in which a plurality of power storage elements, each having an electrode terminal, are arranged, the connection module comprising:
a connection member, an insulation protector, a wire, and a terminal,
wherein the connection member is connected to the electrode terminals,
the insulation protector is assembled with the power storage element group in a state in which the connection member and the wire are accommodated in the insulation protector,
the terminal is configured to be connected to the connection member in a state in which the terminal is connected to an end of the wire,
the insulation protector includes a terminal holding part configured to cover at least a distal end portion of the terminal in a plan view, and
the terminal holding part removably holds the terminal in a state before the terminal is connected to the connection member,
the power storage element group includes an electrode disposition surface on which the electrode terminals are disposed and a battery side wall disposed intersecting with the electrode disposition surface,
the connection member includes a member connection part connected to an external device,
the insulation protector is disposed along the battery side wall and includes a busbar installation wall on which the member connection part is disposed,
the terminal holding part is formed integrally with the busbar installation wall,
the terminal is connected to a terminal connection part that is continuous with the member connection part,
the terminal includes a busbar connection part that makes surface contact with the connection member,
the terminal holding part includes a holding wall and an elastic retaining piece,
the holding wall protrudes toward the busbar installation wall,
the elastic retaining piece is provided in the busbar installation wall so as to be capable of elastic displacement, and
the holding wall and the elastic retaining piece make contact with an outside surface of the busbar connection part and retain the terminal in the terminal holding part.
