In a method of manufacturing a plurality of coil-shaped thin cast strips while molten metal r is being supplied to the molten metal pool 3 formed by a pair of cooling drums 1, 1 and a pair of side dams, when a casting operation corresponding to one coil of the coil-shaped thin cast strip has been completed, gas is made to blow from the gas nozzles 7 b toward the scum s floating on the molten metal, so that the scum s drifts, due to the gas flow to one meniscus m 2 , and the thus drifted scum is attached to a surface of the cast strip and circumferential faces of the cooling drums and is then discharged from the molten metal pool.
