A spherical member polishing apparatus has a fixed disk which is disposed in opposition to a rotating disk with a predetermined clearance. The rotating disk is rotated, and spherical members are clamped and pressurized between the rotating disk and the fixed disk for roll-polishing the spherical members. A plurality of grooves are formed along a circumferential direction of the fixed disk, and a plurality of working-fluid supply ports are randomly formed along the circumferential direction between the grooves, between the groove and an outer peripheral portion of the fixed disk, and between the groove and an inner peripheral portion of the fixed disk. The working fluid is supplied through the working-fluid supply ports to the fixed disk. A large number of spherical members are polished at a high precision, while a variation in polishing precision and the like are avoided as much as possible.
