PROBLEM TO BE SOLVED: To provide a sphere polishing device capable of reducing even number angular spheres and odd number angular spheres in a processed sphere group in one lot to be polished and processed in one process and capable of corresponding to a high precision demand. SOLUTION: Concentric and ring circular arc grooves 9b and V shaped grooves 9a are alternately provided on a fixed board body 8 a specified polishing passage 10 is constituted between them and a rotating board body 7 furnished with a grindstone surface 7a, the polishing passage is divided into a group G1 on the inside in the radial direction and a group G2 on the outside, the sphere supplied to the polishing passage 10 of the group G1 on the inside in the radial direction through a first sorting supply passage 23 is returned to a second sorting carrier passage 17 of a storage conveyor through a first sorting delivery passage 30, and the sphere is supplied to the polishing passage 10 of the group G2 on the outside in the radial direction through a second sorting supply passage 24 different from the first sorting supply passage 23 to which the sphere is delivered immediately before it in a following polishing process.
