PROBLEM TO BE SOLVED: To provide a diffusion disk and a diffusion feeder provided with the disk by which a raw material is widely diffused and fed over a screen. SOLUTION: This diffusion disk 1 is rotated with a rotating shaft 2 as the center, and a raw material dropped on its upper surface is discharged and fed over the reticular face 3 of a screen. The disk 1 is provided with a first diffusion part 10 with the long distance between its peripheral edge and the shaft 2 and a second diffusion part 11 with the short distance between them. The first diffusion part 10 and second diffusion part 11 are formed by providing a recess 9 with a part of the circular or polygonal peripheral edge confronted with the shaft 2.
