PROBLEM TO BE SOLVED: To provide a method for producing an austenitic stainless steel excellent in surface characteristic on a product with which molten steel is poured into a molten steel pool part formed with a part in the periphery of one pair of cooling rolls and side weirs and successively, while cooling and solidifying this molten steel with the rotated peripheral surfaces of the cooling rolls, a thin cast slab is continuously cast with a twin-rolls type casting method. SOLUTION: The molten steel of the austenitic stainless steel having a composition, in which the solidification is completed with the austenite single phase or two phases of the austenite phase and a ferrite phase at the solidifying time, is cast by using the rolls, on which hollow parts having 40-200μm average depth on the peripheral surface of the roll and 0.5-3 mm diameter corresponding to the circle, are formed by mutually adjoining through the top parts of the hollow parts and also, fine holes having≥5μm depth on the surface of the hollow part and 5-200μm diameter corresponding to the circle, are formed at≤300μm pitch.
