PROBLEM TO BE SOLVED: To provide a spray gun capable of easily reproducing a spray pattern having delicate irregularities on a smoothly coated surface. SOLUTION: The spray gun has a coating nozzle 20 spraying a coating and compressed air on an internal mixing system and a ring-like slit 17e arranged around the coating nozzle 20 and spraying compressed air, and the coating and compressed air sprayed from the coating nozzle 20 is mixed with compressed air sprayed from the slit 17e on an external mixing system and sprayed finally. The coating nozzle 20 preferably has an air nozzle 20b inside it, and the compressed air and the coating are mixed inside the tip of the coating nozzle 20 and sprayed. The coating nozzle 20 preferably has an air cap 17 fastened with a screw to the tip of its body 10, the air cap 17 has an insertion hole 17d into which the tip of the coating nozzle 20 is inserted, and the clearance between the inside-diameter portion of the insertion hole 17d and the outside-diameter portion of the coating nozzle 20 constitutes the ring-like slit 17e.
