Abstract

This steel sheet has predetermined chemical composition and microstructure, in a crystal orientation distribution function of a texture at a sheet thickness ¼ position, when A/B that is a ratio of a maximum value A of pole densities at Φ=20° to 60° and φ=30° to 90° in a cross section of φ=45° to a maximum value B of pole densities at Φ=120° to 60° and φ=30° to 90° in the cross section of φ=45° is 1.50 or less, a total of the maximum value A and the maximum value B is 6.00 or less, and a tensile strength is 1030 MPa or more.
