A coating apparatus has a rotary atomizing head that discharges paint to a work, and an air injecting unit that injects annular shaping air towards an outer peripheral edge portion of the rotary atomizing head. The air injecting unit has first air injecting ports and second air injecting ports. First air of relatively high wind speed is injected from the first air injecting ports and second air of relatively low wind speed is injected from the second air injecting ports.
