1. A power storage module comprising:
power storage elements having electrode surfaces of positive electrode surfaces and negative electrode surfaces on front and back surfaces thereof;
a conductive member electrically connected to the electrode surfaces of the power storage elements; and
a wiring module electrically connected to the conductive member, wherein
the power storage elements are arranged in an arrangement direction such that the electrode surfaces of the power storage elements that are adjacent to each other are opposed to each other,
the electrode surfaces of the power storage elements that are adjacent to each other are electrically connected by the conductive member that is disposed between the power storage elements that are adjacent to each other,
the wiring module is disposed between the power storage elements that are adjacent to each other,
the conductive member and the wiring module are disposed inside an outline of the power storage elements seen from the arrangement direction,
the wiring module includes a housing having insulating properties, a terminal arranged in the housing, and an electric wire connected to the terminal,
the terminal includes an elastic contact portion that is elastically deformable, the conductive member has a terminal contact surface on a side edge that is not contacted with one of the electrode surfaces,
the elastic contact portion of the terminal is to be elastically contacted with the terminal contact surface,
with the wiring module and the conductive member being coupled together, the terminal is disposed in the housing to be movable between a contact position in which the elastic contact portion is in contact with the terminal contact surface of the conductive member and a standby position in which the elastic contact portion is away from the terminal contact surface of the conductive member,
the housing includes a standby position stopper for holding the terminal in the standby position and a contact position stopper for holding the terminal in the contact position,
the housing includes a window hole in a section thereof corresponding to the terminal,
the housing further includes a terminal cover that covers the window hole and is movable between a temporary holding position and a holding position,
the terminal cover includes a first holder for holding the terminal in the standby position with the terminal cover being held in the temporary holding position and a second holder for holding the terminal in the contact position with the terminal cover being held in the holding position, and
the electrode surfaces are terminals.
