PROBLEM TO BE SOLVED: To provide a spray head for spraying a granular agent which increases the flying distance of the granular agent. SOLUTION: A spray head for spraying a granular agent has spray head tubes 1 through which the agent is supplied, the first spray opening 6 which is formed between the tubes 1 to protrude inward and discharges the agent in a prescribed direction, and the second spray opening 7 opened in the axial direction at the tip. The cross-sectional area of the second spray opening 7 is equalized to that of a part where the conduit of the spray head tube 1 is minimized by the inward protrusion of the first spray opening 6.
