PROBLEM TO BE SOLVED: To provide a method with which development of defective characteristic in a strip at the initial stage of casting is restrained with a simple means and the good strip can be produced at good yield by dissolving a trouble and the wide strip and mass-production can be applied. SOLUTION: Spouting pressure when molten metal is spouted on the circumferential surface of a cooling roll, is changed and in an interval from the starting time of the casting to obtaining of a stationary range for stabilizing the casting, a stabilizing range becoming in a prescribed range, in which the spouting pressure is lower than that in the stationary range is arranged. It is desirable that the stationary range having a fixed spouting pressure is arranged just after starting the casting and thereafter, the spouting pressure is gradually increased and shifted to the above stationary range having the fixed spouting pressure. In this time, the control of the spouting pressure can be obtained with the simple means for adjusting the molten metal height in a tundish and this method can be applied to the wide strip and the mass-production and improvements of a producing yield and a productivity can be achieved.
