By unitizing the voltage measurement terminals for the fuel cell stack, the voltage measurement terminals are not individually attached to the separators, but all the separators (or the separators to which the voltage measurement terminals need to be attached) are connected together at once. Therefore, the work of connecting the voltage measuring terminal to the separator can be performed with high efficiency and can be simplified. By interposing an elastic member between the voltage measuring terminal and the terminal fixing plate in the unit, it is possible to absorb a minute step (unevenness) of the separator due to a stacking deviation. Further, by providing the voltage measuring terminal mounting portion of the terminal fixing plate with the elongated hole, the electronic measuring terminal can be minutely moved in the stacking direction, and the minute deviation of the separator during stacking and stacking can be covered. Further, by providing the engaging concave portion at the position in contact with the voltage measuring terminal in the separator, the displacement of the voltage measuring terminal can be prevented and the connection state can be stabilized.
