PROBLEM TO BE SOLVED: To provide an impeller of a centrifugal projection device capable of easily changing a blade having projection distribution appropriate for a product to be processed in a short period of time. SOLUTION: In the impeller of the centrifugal projection device, a plurality of blades are radially arranged between a first rotary plate and a second rotary plate at a hub side which are attached to a driving shaft of a driving means via a hub and facing against each other. In the impeller of the centrifugal projection device for projecting a projection material released to a projection area formed between the blades by a turning centrifugal force of the blades, the first rotary plate and the blades are integrally manufactured.
