Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cut part having roundness suitable for a cold-rolling without defective waving, burr, flaw, etc., and to eliminate the flaw of a rolling roll and the breakage of a metallic thin sheet at the time of cold-rolling caused by the burr and the flaw at the cut part. SOLUTION: This cutting work is provided with a process for forming straight grooves 16 extended in the longitudinal direction in the hot state so as to have prescribed remaining thickness at relative positions in the width direction on the front and the back surfaces of the metallic thin sheet 14 continuously cast and a process for finally cutting the straight groove parts of the metallic sheet 14 with an abrasive water jet 17 of executing cutting by jetting the compressed water containing the abrasive powder 27.
