PROBLEM TO BE SOLVED: To provide a high workability medium or high carbon steel sheet excellent in local ductility such as stretch flanging properties. SOLUTION: This medium or high carbon steel sheet excellent in local ductility, which is composed of steel of 0.10 to 0.80 mass % C, and in which carbides are dispersed into ferrite in such a manner that the dispersing degree of the carbides is controlled to 75-47×(C%)(2/3)}% or less, is provided. By controlling the average grain size of the carbides, its local ductility moreover improves. The one in which Si, Mn, Cr, Mo, Cu, Ni or the like are suitably added as steel components may be used.
