PROBLEM TO BE SOLVED: To provide a scattering plate, a grinding wheel, and a grinder that can elongate a scattering distance of a supply liquid in a supply direction while suppressing an increase in cost with a simple constitution.SOLUTION: A scattering plate 4, which scatters a supply liquid supplied via a supply pipe, comprises a plate-like member 41 that can be arranged so as to be nearly parallel to a supply direction D1 of the supply liquid in a thickness direction at a position counter to the opening end of the supply pipe, and so as to rotate on a rotation axis nearly parallel to the thickness direction. The plate-like member 41 comprises a scattering hole 42 which penetrates in the thickness direction to enable the supply liquid to pass through at a point other than the rotation center O of the plate-like member 41. A wall surface 421 located on the rear side of the scattering hole 42 in a rotation direction D2 is inclined so that a wall surface end part 421A located on the rearmost side in the rotation direction of the side of a counter face 411 counter to the supply pipe 3 may be located in the rotation direction D2 ahead of a wall surface end part 421B located on the rearmost side in the rotation direction of the side of a non-counter face 412. |
