摘要： A corona control ring has a corona control ring main body and a water discharge hole having an elongated shape like a racetrack. The corona control ring main body includes a bottom portion and an inner wall portion and an outer wall portion respectively arranged at an inner edge portion and an outer edge portion of the bottom portion. The water discharge hole is arranged in the bottom portion. A depression portion is formed in the corona control ring main body by the inner wall portion, the outer wall portion and the bottom portion. Accordingly, the present invention provides a corona control ring which can suppress a corona discharge even during rain fall.
