PURPOSE: To strenghen binding between a pole main body and each frame and prevent an alternating current of electrolyte by binding an insulating frame body to the pole main body through an intermediate frame.
CONSTITUTION: In a bipolar pole plate for layer-built cell which is formed with a pole main body 1 in a flat plate shape and an insulating frame body 3 made of synthetic resin which is formed integratedly on the outer circumferential edge part of the pole 1, the insulating frame body 3 is formed of the resin containing glass fiber in its synthetic resin. In addition, an intermediate frame 2 which is made of the same synthetic resin as the insulating frame body 3 containing no glass fiber is integratedly formed between the insulating frame body 3 and the outer circumferential edge part of the pole main body 1. Thus, binding between the pole main body 1 and the intermediate frame 2 as well as between the insulating frame body 3 and the intermediate frame 2 can be improved and the whole can be strengthened.
