PROBLEM TO BE SOLVED: To securely deposit a sufficient amount of a conductive active material layer of a lead dioxide system on an electrode base material and eventually provide an electrode having high performance and long life. SOLUTION: According to the structure of the electrode 201, even if trouble, such as consumption or damage, occurs in part of electrode segments 211 and 250 by the use of the electrode segments 211 and 250, repair may be easily carried out simply by exchanging only the electrode segments 211 and 250 having the trouble. On the other hand, a net like corrosion resistant base material is used as the base material (electrode base material) of the electrode segments 211 and 250 and since the conductive active material layer composed mainly of the lead dioxide is deposited in the wire-shaped segment forming their mesh, the deposition area per unit weight of the conductive active material increases and eventually the adhesive strength of the conductive active material to the electrode base material may be increased. As a result, the peeling, dislodgment, etc., of the conductive active material during the treatment, such as plating, hardly occurs. Since the deposition amount of the conductive active material layer to the base material surface may be made relatively larger, the electrode life may be extended.
