Provided is a pass schedule setting method for rolling an object plate. The method comprises a step of setting the total number of rolling passes, a step of assuming a plurality of pass schedules for the total number of rolling passes, a step of utilizing, for each of the pass schedules, an evaluation function which uses as an index the value obtained by dividing the difference between a characteristic value of the object plate in each pass and the ideal value for the characteristic value by the power multiplication of the exit-side plate thickness of each pass, and a step of setting a schedule which has the smallest evaluation function among the pass schedules.
