Abstract
The present invention provides a metal sheet rolling method of rolling a metal sheet with a pair of rolls, as well as a rolled sheet manufactured by the metal sheet rolling method. In the metal sheet rolling method, respective interfaces between the pair of rolls and the metal sheet have mutually different frictions. Additionally at least one of the interfaces may be lubricated by a procedure other than lubrication by coating of a liquid lubricant agent. Alternatively at least one of the interfaces may be subjected to surface treatment by a procedure other than lubrication, or otherwise the pair of rolls may be made of mutually different materials.
