Comprises a flat conductive fiber assembly 1, a silicone-based resin sheet 2 that is impregnated and solidified to the extent that the surface of the fiber assembly 1 is exposed, and a hard resin frame 3 that fixes the silicone-based resin sheet 2. Become. In the bipolar partition sheet 6 having such a configuration, the oxygen atoms in the molecule of the silicone-based resin sheet 2 are strongly bonded to the oxide film formed on the surface of the conductive fiber assembly 1, so that the durability (acid resistance) is improved. ), And since the silicone-based resin sheet 2 has flexibility, the contact surface between the conductive fiber assembly 1 and the resin sheet 2 is not easily peeled off even when the sheet is deformed, and the coefficient of thermal expansion of the fiber and resin is high. Even if there is a difference in temperature, the contact surface between the fiber and resin does not easily peel off due to temperature changes. Further, in the present invention, even when the silicone resin sheet is adhered or adhered to the hard plastic frame, the silicone resin sheet can be strongly adhered even if there is a difference in thermal expansion coefficient between them.
