A rotary electrostatic atomizer is capable of changing the coating pattern width. Shaping air outlets (1) are aligned on a circle concentric with the rotation axis line (L) of a rotary head, and pattern control air outlets (3) are provided on a circle concentrically surrounding the alignment of the shaping air outlets (1). The shaping air outlets (1) and the pattern control air outlets (3) incline around the rotation axis line (L) such that shaping air (5) from the shaping air outlets (1) and pattern control air (6) from the pattern control air outlets (3) make spiral air flows twirling in the same direction. Angle (.beta.) of inclination of the pattern control air (6) is larger in absolute value than angle (.alpha.) of inclination of the shaping air. |
