PROBLEM TO BE SOLVED: To provide an pneumatic sorter having high sorting accuracy in which the heights of a spare chamber and a sorting chamber can be easily and efficiently changed with simple constitution. SOLUTION: The pneumatic sorter is provided, in a body (10), with: a sorting plate (30); a guide plate (40) arranged at a position above and opposite to the sorting plate (30); the sorting chamber (12) formed between the guide plate (40) and the sorting plate (30); and a cylindrical dispersion chamber (13) formed above the guide plate (40). The guide plate (40) is vertically movably held by an elevation shaft (45) at the distal end part of the elevation shaft (45) protruded to the inside of the dispersion chamber (13) through the upper center of the body (10), thus, the dispersion chamber (13) is formed axisymmetrical, and further, by vertically moving the guide plate (40), a spacing between the guide plate (40) and the sorting plate (30) is adjusted, so that the volume of the sorting chamber (12) is made variable.
