PURPOSE:To provide a double-pole partition sheet excellent in durability and flexibility, capable of preventing any leakage of an electrolyte staying on both surfaces of the bipolar partition sheet for a long period. CONSTITUTION:A double-pole partition sheet 6 is constituted of a sheet-like conductive fiber collective body 1, and an adhesive resin 2 made of a soft silicon resin and capable of being impregnated and solidified to such an extent that the surface of the sheet-like conductive fiber collective body 1 is exposed. Accordingly, the resin sheet can be firmly bonded to the conductive fiber collective body 1, and is excellent in durability (acid resistance) owing to its own flexibility. Furthermore, it is possible to prevent separation of the fiber from the contact surface with the resin due to deformation of the sheet or variation in temperature so as to prevent any leakage of an electrolyte for a long period. |
