PROBLEM TO BE SOLVED: To provide an apparatus for distributing powder, capable of uniformly distributing powdery biological pesticide on a field for cultivating farm products. SOLUTION: The apparatus 1 for distributing the powder can distribute the powder uniformly by making nearly equal the amount of the powder to be distributed from each distributing hole 5 by the regulation of output of a blower 2 because the caliber of a distributing hole 5 bored in a distributing cylinder 4 is formed so as to be gradually increased to the tip part in the longitudinal direction of the distributing cylinder 4. The uniformity of the distribution of the powder can be heightened because the distributing holes 5 of the distributing cylinder 4 are bored so as to change the directions intermittently at 45°elevation angle to enable the powder flow to be gushed to a high position from the ground.
