Abstract
A rotary atomizing head () is mounted on a fore end side of a motor (). A shaping air ring () having a plurality of air outlet holes () at fixed intervals is provided on a rear side of the rotary atomizing head (). Outer surfaces of the air motor () and outer surfaces of the shaping air ring () are enshrouded over the entire circumference by a cover member () formed of an electrically insulating material. An external electrode assembly () is provided radially outwardly of the cover member (). An annular projecting portion () which projects forward is provided on the shaping air ring () over the entire circumference. The air outlet holes () are open in a fore distal end of this annular projecting portion (). As a result, a corona discharge can be generated by allowing an electric field to be concentrated at the fore distal end of the annular protecting portion ().
