PROBLEM TO BE SOLVED: To provide a grinding method of a rolling-mill roll by which a cemented carbide-made rolling-mill roll can be ground uniformly and efficiently, and a cold rolling method by which a highly glossy cold rolled steel sheet excellent in a uniformity in appearance is obtained. SOLUTION: A grind working face of a grindstone is brought into contact with the rolling-mill roll by crossing a grindstone turning shaft and a rolling shaft using a cap-like diamond wheel as the grindstone, in the grinding method for grinding the rolling-mill roll by turning the cemented carbide-made rolling-mill roll, and also by bringing into contact with the rolling-mill roll while turning the grindstone and by moving along the rolling axis.
