PROBLEM TO BE SOLVED: To provide an atomization device of an air spray gun for reducing unevenness formed during spraying, and eliminating formation of coating with an uneven thickness to a surface to be coated, and capable of coating without unevenness in thin film coating using a low viscosity paint or the like and forming a high quality coated surface. SOLUTION: There is provided an atomization structure of an air spray gun in which a plurality of vertical caves 33 that are opened substantially parallel to a center axis of a paint nozzle 3 are provided as a path for supplying air from a center air chamber 13 of a gun body 1 to a center air outlet 42 of an air cap 4, and shielding plates 34, 35 in a collar shape for shielding air from each of the vertical caves 33 from going straight ahead to an outlet portion in the air cap side of each of the vertical caves 33 and directing to an outer periphery of the shielding plates 34, 35 are provided so that an annular concentric path having an axial length and a sufficient volume is formed in order to form a more uniform air flow after air flowing around the outer periphery of the shielding plates 34, 35 reached thereto.
