To provide a method for rolling a thick plate and a rolling apparatus by which the variation in the finishing temperature and the finishing thickness after a finish rolling stage cab be reduced.

When a predicted finishing temperature which is calculated on the basis of the actual temperature of a material to be rolled just after a rough rolling stage is higher than the target finishing temperature which is beforehand planned as a finishing rolling schedule in the finish rolling stage, the finish rolling schedule is recalculated on the basis of the difference between the predicted finishing temperature and the target finishing temperature, and the finish rolling stage is performed while performing temperature lowering processing for lowering the temperature of the material to be rolled on the basis of the recalculated finish rolling schedule. When the predicted finishing temperature is lower than the target finishing temperature, the finish rolling schedule is recalculated on the basis of the difference between the predicted finishing temperature and the target finishing temperature, and the finish rolling stage is performed while performing temperature maintaining processing for maintaining the temperature of the material to be rolled on the basis of the recalculated finish rolling schedule.
