The utility model discloses a finish-lapping oilstone for a logarithmic convexity tapered roller. Two faces of the cuboid oilstone in the length direction are both constituted by inner concave curvedsurfaces; two curved surfaces in the same shape are symmetrically distributed; and the third face of the cuboid oilstone in the length direction is an equal-diameter concave curved surface of which the radius equals to the radius of the tapered roller. A grinding theory considers that the workpiece resection amount is proportional to the contact arc length; the amount to be ground calculated by alogarithmic convexity curve is used to design the oilstone structure; and the required logarithmic convexity can be obtained after the roller is ground and processed by the oilstone. By adopting the oilstone with the structure to process the convexity of the roller, the required processing equipment is simple, the cost is low, and the operation is simple and convenient; and furthermore, the difficult problems that the loga
