PROBLEM TO BE SOLVED: To provide a steel sheet having excellent surface properties which has no surface defects caused by the remaining of scale near the corner part of a slab on rough rolling and whose production cost is also low, and a production method therefor. SOLUTION: The steel sheet comprises, by mass, ≤0.1% C, ≤1% Si, 0.1 to 2.5% Mn and ≤0.03% S, and the surface roughness Rz of the steel sheet is a region where the surface roughness Rz is ≥10μm is a region other than the above region is COPYRIGHT: (C)2006,JPOandNCIPI
