Provided is a spray gun (1) which can achieve pattern uniformity of a coating material. The spray gun (1) is provided with: a gun main body (10) which has a paint spray nozzle (20); multiple pattern spray nozzles (50) which spray air approximately parallel with the paint spray direction; and a cap (52) which comprises a center opening end (52H) which has an opening greater than or equal to the outer diameter of the paint spray nozzle (20), and an inner wall surface (52W) which communicates with the center opening end (52H) and is inclined such that the inner diameter increases in the paint spray direction, and which has multiple granularity adjustment nozzles (55) which are formed in the inner wall surface (52W) and spray air to adjust the granularity of the paint. The granularity adjustment nozzles (55) are formed such that the axis lines thereof are at a prescribed angle of inclination relative to the axis line of the paint spray direction of the paint spray nozzle (20), and in the cap (52), slits (60) are formed for supplying air towards the pattern spray nozzles (50). |
