PROBLEM TO BE SOLVED: To provide a cold rolling method of a metal plate, configured to prevent a threading trouble such as fracture or squeezing in the rolling at low cost, and to provide a method of manufacturing the metal plate using the same.SOLUTION: A cold rolling method of a metal plate includes: cold-rolling a rolled material using a rolling mill that is set to form an ear wave shape, when a deformation resistance at the end in a width direction of the rolled material is higher than the deformation resistance at the center in the width direction; and cold-rolling the rolled material using the rolling mill that is set to form a center buckle shape, when the deformation resistance at the end in the width direction of the rolled material is lower than the deformation resistance at the center in the width direction. The method of manufacturing the metal plate has a step of cold-rolling the metal plate using the cold rolling method of the metal plate. |
