An air atomization cap of a spray gun is provided to equally keep a center spray flow with paints, level by narrowing an inlet unit of a water port of a horn part. The air atomization cap(4) assembled to an air spray gun atomizing paints by the compressed air is composed of a center air hole(42) formed in a ring shape by an outer peripheral part of a paint ejection port(9) disposed in the center; a pair of horn parts(43) symmetrically installed at the outside of the center air hole; and side air holes(44) crossing each other from the horn part to the center at an obtuse angle and forming spray patterns by jetting the side air. Each sectional area of inlet units of water ports(47) formed at each horn part with communicating with the side air holes is smaller than a sectional area of a passage of the water port communicating with the side air hole.
