PROBLEM TO BE SOLVED: To provide an external electrode structure, which can be fixed safely on a concrete surface easily and surely, by which fixing workhours are also shortened and which can also be applied to a concrete structure with a curved surface or an irregular surface and the concrete structure on the beach particularly and is used for an electrochemical desalting method and/or a re- alkalinization method. SOLUTION: In the external electrode structure, a cutoff sealing material is provided around the concrete structure through an easily peelable uneven correction material, a covering material, a sag preventive material and a clamping member are laminated and fixed from the upper section of an electrode through spacers, and a section between the covering material and a concrete surface is filled with an electrolyte.
