A manufacturing apparatus comprises a final stand, with standing side members, and a cooling apparatus. The cooling apparatus comprises rows of upper surface cooling nozzles, rows of lower surface cooling nozzles, and an upper surface guide on the upper surface side of the steel sheet. An end portion of the cooling apparatus on a side of the final stand is arranged between the standing side members of the housing. When defining a width of a uniformly cooled region, an average gap distance (WSW) between the end portion of the width of the uniformly cooled region and the standing side member of the housing; a gravity acceleration rate, an average water volume density of the width of the uniformly cooled region, and a value determined by WSW and an average distance h between the upper surface guide and the upper surface of the steel sheet, a specific relation is satisfied. |
