Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a corrosion prevention method for a concrete utility pole for preventing corrosion of a reinforcement steel member in concrete utility pole and streetlight for a long time. SOLUTION: In this corrosion prevention method for the concrete utility pole manufactured by using concrete and reinforcement, cation electrodeposition coating is applied to the reinforcement before manufacturing the utility pole, thereby preventing corrosion of the reinforcement steel member for a long time because coating reaches up to a thin part-a small clearance part of the reinforcement and reducing burden of labor and cost required by the work for replacing the concrete columnar structure being necessary as a result of its use for a long time.
