PROBLEM TO BE SOLVED: To provide a means for obtaining an optical lens having a desired optical surface by polishing a surface to be polished of a variety of surface shapes without large variation in a polishing amount within the surface. SOLUTION: The method for manufacturing an optical lens includes relatively moving a polishing tool having a projection formed of an elastic material and a molding formed into a lens shape having a concave surface while supplying polishing agent to a gap between the projection of the polishing tool and the concave surface of the molding and thereby polishing the concave surface. As the polishing tool, a polishing tool satisfying (1) and (2) below is to be selectively used. (1) The polishing tool has such a shape that, when the projection of the polishing tool is fitted with the concave surface of the molding of a polishing object, the both contact with each other in the center part, however they separate from each other in the peripheral part. (2) When the projection of the polishing tool is fitted with the concave surface of the molding of the polishing object in a state a reference axis on the concave surface and a reference axis on the projection oppose with each other, the separation distance in the peripheral part is a predetermined allowable separation distance or less.
