Abstract

This steel sheet contains, in terms of mass%, up to 0.0060% C, 0.0010-0.050% Si, 0.05-0.50% Mn, 0.005-0.100% P, up to 0.0500% S, 0.0010-0.010% Al, 0.010-0.045% Cu, 0.0250-0.0700% O, and 0.0010-0.0045% N, with the remainder comprising Fe and unavoidable impurities. The steel sheet has a structure which comprises ferrite, and the ferrite located at a sheet-thickness-direction depth corresponding to 1/4 the sheet thickness from a surface of the steel sheet has an average crystal-grain diameter of 20.0 µm or smaller. The structure contains oxides containing Fe and Mn. Among the oxides, the number density of the oxides having diameters larger than 1.0 µm but not larger than 10 µm is 1.0x103-5.0x104 grains/mm2, and the number density of the oxides having diameters of 0.1-1.0 µm is 5.0x103 grains/mm2 or greater.
