PROBLEM TO BE SOLVED: To perform highly accurate polishing by correcting a wear of an abrasive plate caused by polishing a polished object in line with actual polishing. SOLUTION: This spherical surface grinding/polishing device is equipped with the abrasive plate 2 for polishing a spherical surface of the polished object 1, a rotating means 3 for holding and rotating the plate 2, a holding means 4 for rotatably holding the means 3, a rocking means 12 for causing the plate 2 to make rocking motion, a pressing means for pressing the object 1 toward the spherical center of the plate 2 while rotatably holding it, a moving means 11 for moving the means 4 toward or away from the plate 2, a detecting means 18 for detecting the height of the plate 2, and a control means 22 for controlling the means 11 based on a detection value of the means 18 to correct the height of the plate 2.
