PROBLEM TO BE SOLVED: To obtain high corrosion inhibition effect and insulating properties and a long service life by providing a discharge material composed of lead base metal joined to the surface side of a base material composed of iron, copper and titanium base metal and a flake lining layer obtd. by dispersing flakes such as glass into a resin on a non-discharge face including the exposed face of the base material. SOLUTION: An electrode lining 10 for electrolysis is composed in such a manner that a discharge material 12 of lead or a lead alloy joined to the surface side of a base material 11 of iron, copper, titanium or the alloys thereof is provided, a flake lining layer 13 small in soln. permeability and obtd. by dispersing flakes into a resin is provided on a non-discharge face including the exposed face of the base material 11, and furthermore, an FRP lining layer 14 composed of fiber reinforcing resins is laminated on the outside thereof. Since the flake lining layer 13 is provided, the permeation of an electrolytic soln. is prevented, the erosion of the base material is prevented, the insulating properties thereof is increased, and the service life of the electrode can be prolonged.
