Zusammenfassung:	PROBLEM TO BE SOLVED: To precisely recognize the consumption loss of the anode by providing an indicator cavity contg. an electric wire provided with an indicator connection. SOLUTION: The entire surface of an indicator rod 4 is insulated 5. The color indicators 6a, 6b and 6c each consisting of plural different color bands are formed in the axial direction. The rod is simultaneously insulated 5 and coated with a clored heat-resistant paint or a colored ceramic to form the color indicators 6a, 6b and 6c. The indicator cavity contg. an electric wire provided with an indicator connection is furnished in a galvanic corrosion preventive anode. The anode 1 is formed with an anode main body 2 and a core 3, and the rod 4 is welded to the core 3. Consequently, a great deal of labor is not needed, and the consumption loss is precisely recognized.
