ABSTRACT OF THE DISCLOSURE A bipolar electrode comprising (a) an anode member comprising a substrate made of an anticorrosive metal or metal alloy and an electrically conductive coating formed on the surface thereof; (b) a cathode member comprising a metal or a metal alloy; (c) a partition wall for separating the anode member from the cathode member, the partition wall comprising an anode- side sheet made of the same type of anticorrosive metal or metal alloy used as the substrate of the anode member and a cathode- side sheet made of the same type of metal or metal alloy used as the cathode member; and (d) a composite member for electrically and structurally connecting the anode member and the cathode member to each other, the composite member comprising bonded together (i) an anode- side portion made of the same type of anticorrosive metal or metal alloy used as the substrate of the anode member, (ii) a cathode- side portion made of the same type of metal or metal alloy used as the cathode member, and (iii), as an interlayer, a portion made of an electrically conductive metal or metal alloy, which is resist- ant to the migration of hydrogen and is substantially impermeable to atomic hydrogen, wherein (1) pins made of an electrically con- ductive metal or metal alloy, which is resistant to the migration of hydrogen and is substantially impermeable to atomic hydrogen, are caulk-fitted in through-holes provided in the composite member (d), the through-holes outwardly diverging toward both surfaces of the composite member (d) so that the pins (1) adhere closely to the inside surfaces of the through-holes in the com- posite member (d), (2) the anode-side sheet and the cathode-side sheet of the partition wall (c) are sheets having no through- holes for inserting the composite member.
