Abstract

In a hot-rolled sheet, an average value of pole densities of an orientation group {100}<011> to {223}<110>, which is represented by an arithmetic mean of pole densities of orientations {100}<011>, {116}<110>, {114}<110>, {Il2}<ll0>, and {223 }<110> in a thickness center portion of a thickness range of 5/8 to 3/8 from a surface of the steel sheet, is 1.0 to 6.5 and a pole density of a crystal orientation . {332}<113> is 1.0 to 5.0; and a Lankford value rC in a direction perpendicular to a rolling direction is 0.70 to 1.10 and a Lankford value r30 in a direction that forms 30° with respect to the rolling direction is 0.70 to 1.10.
