The average value of the X-ray random intensity ratios of the {100} <011> to {223} <110> defense groups on the plate was 3.0 or more, and {554} <225>, {111} <112>, and {111} <110> An average value of the X-ray random intensity ratios of three crystal orientations is 3.5 or less, and at least one of the r value of a rolling direction and the perpendicular | vertical direction is 0.7 or less, The ferritic steel plate characterized by the above-mentioned. |
