         6 . An electrode as claimed in  claim 5 , wherein at least a top part of the conducting bar dips below an upper surface of the plate. 
     
     
         7 . An electrode as claimed in  claim 3 , wherein the conducting bar has a first portion and a second portion substantially in axial alignment, a third portion axially offset from the first portion and the second portion, a fourth portion disposed between the first portion and the third portion and a fifth portion disposed between the second portion and the third portion. 
     
     
         8 . An electrode as claimed in  claim 7 , wherein the axis of the third portion is below the level of the axes of the first portion and the second portion. 
     
     
         9 . An electrode as claimed in  claim 7 , wherein the plate is attached to the third portion. 
     
     
         10 . An electrode as claimed in  claim 3 , wherein the conducting bar has a tubular shape and the conducting member is welded to an inner surface of the conducting bar. 
     
     
         11 . An electrode as claimed in  claim 3 , wherein the electrode is a cathode used for electrolytic processes of copper production. 
     
     
         12 . An electrode as claimed in  claim 3 , wherein the conducting bar is made of stainless steel. 
     
     
         13 . A hollow conducting bar for an electrode, the hollow conducting bar having:
 a first and second portion substantially in axial alignment; and   a third inclined portion and a fourth inclined portion disposed between the first and second portions;   wherein the axes of the third inclined portion and fourth inclined portion are angled relative to the axes of the first and second portions, and wherein a conducting member is attached to an inside surface of the conducting bar.   
     
     
         14 . An electrode or a hollow conducting bar as claimed in  claim 13 , wherein the conducting bar is formed by roll forming. 
     
     
         15 . A method of manufacturing an electrode, the method including the steps of:
 attaching a conducting member to an inside surface of a conducting bar; and   attaching a plate to the conducting bar.   
     
     
         16 . A method as claimed in  claim 15 , further including the step of forming the conducting bar such that a first and second portion of the conducting bar are substantially in axial alignment, a third portion of the conducting bar is axially offset from the first and second portion, a fourth portion of the conducting bar is disposed between the second and third portion. 
     
     
         17 . A method as claimed in  claim 15 , further including the step of forming the conducting bar such that a first and second portion of the conducting bar are substantially in axial alignment, a third inclined portion and fourth inclined portion of the conducting bar are disposed between the first and second portions, wherein the axes of the third inclined portion and the fourth inclined portion are angled relative to the axes of the first and second portions. 
     
     
         18 . A method as claimed in  claim 17 , wherein the third inclined portion and the fourth inclined portion form an obtuse angle. 
     
     
         19 . A method as claimed in  claim 18 , wherein the third inclined portion and the fourth inclined portion form a right angle or an acute angle. 
     
     
         20 . A method as claimed in  claim 16  wherein the step of attaching a conducting member to an inside surface of a conducting bar involves welding the conducting member to an inside surface of the conducting bar before the conducting bar is formed. 
     
     
         21 . A method as claimed in  claim 16 , wherein the step of forming the conducting bar involves roll forming the conducting bar.
